c 2 vultures, should be divided or multiplied first

Here 2 is a whole, very simple example. 24÷12=2。The 12 here is a whole. If, according to some people's thinking, 24 12 = 24 6*2, it should be equal to 8, and if there is something like omitting the sign in the formula, it is regarded as a whole.

Division first, then multiplication 2 is a multiplier sign, if you calculate 2 first should add parentheses to c (2).

c denotes the circumference of the circle, according to c=2r, c2=r. If you want to find the radius, you should first calculate 2, that is, 2

In general, the multiplication of numbers by letters, the multiplication of numbers by roots and the multiplication of numbers by special constants, and the multiplication sign are all required to be omitted and considered as a whole, without additional parentheses.

For example, 2a, 3, 2, 4e, 5, etc.

2 vultures are a whole and are equivalent to c (2 vultures).

Normally, multiplication and division is the equivalent notation, calculated from left to right (i.e., division first), but here, 2 represents a number, and multiplication (2) followed by division (c 2) should be calculated.

This equation actually knows the circumference of the circle and finds the radius, which is generally written as c vultures 2

c (2), write like that, and you yourself will understand.

Generally, 2 is regarded as a number, so multiplication is calculated first.

Answer: According to the four algorithms, the division should be calculated first.

In principle, it is calculated from left to right, that is, division is calculated first and then multiplication, which is equal to 9.

If there is only multiplication and division without addition and subtraction and no parentheses, it is done in the order of the question itself.

Therefore, this question divides first and then subtracts.

Calculate from left to right, and those with parentheses are counted in parentheses first.

Solution: When calculating 32 4 2, the division should be calculated first and then multiplied in order from left to right.

1. The first digit is the same, and the sum of the two mantissa numbers is equal to 10 The two-digit multiplication method: Ten digits plus 1, the resulting sum is multiplied by the ten digits, and the number is the first product, and the single digit is multiplied, and the number is the back product, and no ten digits are made up with 0.

2. The first digit is the same, and the mantissa is not equal to 10 two-digit multiplication method: the two first digits are multiplied (that is, the square of the first digitude), the number is taken as the front product, the sum of the two mantissa numbers is multiplied by the first place, the number is taken as the middle product, the full ten is one, the two mantissa are multiplied, and the number is taken as the back product.

3. The multiplier is the same, and the multiplier is 10 two-digit multiplication method: the first multiplier is added to 1, and the sum obtained is multiplied by the first digit of the multiplier, and the number is the first product, and the two mantissa numbers are multiplied, and the number is the back product, and there are no ten digits with 0 to make up.

4. The sum of the first and last digits of the multiplier is 10, and the multiplication method of the first and last digits of the multiplier is the same: similar to the method of helping 6. The product of the two first digits multiplied plus the single digit of the multiplier, the number is taken as the first product, and the two mantissa numbers are multiplied, and the number is taken as the back product, and there is no ten digits to make up 0.

If the column formula is not bracketed, it is generally calculated before and then after, in this case, it is calculated first and then multiplied.

It is okay to divide or calculate the Chengdu first. Addition and subtraction mixing or multiplication and division mixing change the order of operations without affecting the result. Generally speaking, it can be calculated as simple as it is.

32 4 2 Whether to divide or multiply first This should be calculated in turn, first division and then multiplication; If 4 2 has parentheses, you should calculate the multiplication in the parentheses first; The answer is 16

In such a situation, of course, it is enough to follow the order, so it must be calculated first and then multiplied.

Divide first and then multiply, because multiplication and division are sibling operations, and the order of sibling operations is from left to right.

This is a related problem in elementary school mathematics, which belongs to the category of multiplication and division mixed operations, in this case, according to the rules of mathematics, from left to right, that is, first calculate the division and then multiply the obtained result, that is, first calculate the result of division is equal to 8, and then use 8 times 2 to achieve equal to 16

In this problem, division is calculated first, because the priority of multiplication and division is the same, and when they appear together, they are counted from left to right. 32 4 is on the left, so it should be counted first. The result of 32 4 2 is 16.

When calculating 32 4x2, it is not right to calculate multiplication first and then division, the order is from left to right, and division must be calculated first and then multiplication.

According to the calculation of this problem, the arithmetic should be the division first, then the multiplication, and this order can be changed if simple calculations can be used. It's all about making the calculations easier.

The division sign and the multiplication sign have the same priority in the equation, and in the case of the same priority, calculate from left to right, and calculate 32 4 first.

This is calculated in order.

That is, division first, and then multiplication.

So the correct answer to this question is equal to 16, and I hope it can help you.

When multiplication and division are mixed together, divide and then multiply according to the order in which they are present.

This problem is a mixed operation of multiplication and division, because multiplication and division are operations of the same level, so they are usually calculated from left to right, so this problem first calculates division and then multiplication.

Of course, it is to divide first and then multiply, and then calculate in turn.

If there is both division and multiplication in this equation, then it can be calculated in this order.

This equation should be calculated from the front to the back, so that it is correct, and it cannot be calculated from the back to the front, because the result is not the same.

If it is all multiplication and division, it is calculated in order from left to right, and the parentheses are counted first, 32 4 2 8 2 16

Divide first and then multiply.

Because multiplication and division are second-order operations, the order of siblings is from left to right.

Multiplication and division have equal priority, so when encountering an arithmetic with both multiplication and division, it will be in order from left to right, so this problem will calculate division first, and then multiplication.

From left to right, 399 7 23

This question must be calculated and divided first, and whoever is in front will be counted first.

16x2 2 first calculate the multiplication, then change the cavity and then take the annihilation shed to calculate the division.

The calculation process is as follows:

16x2÷2

If there is only multiplication and division in the question, it is calculated in order, that is, if the multiplication comes first, the multiplication is calculated first, and if the division is first, the division is calculated first.

Calculate from left to right, and if there are parentheses, count the ones in parentheses first.

If there is no parenthesis restriction for regular questions, they will be counted in order from left to right.

If there are no parentheses, they are counted in a preceding order.

It's all right, I hope it can help you.

If there are parentheses, count the brackets first, and if there are no parentheses, multiply and divide first, then add or subtract.

Multiply and divide first, then add and subtract, only multiply and divide without parentheses and calculate from left to right.

This should be calculated sequentially, first by division and then by multiplication; If 4 2 has parentheses, you should calculate the multiplication in the parentheses first;

The answer is 16

Count from left to right, divide first and then multiply.

For the sake of simple operation, you can multiply the later equation first, and then divide by the formula.

If there are parentheses, the formula is calculated first, and if there are no parentheses, multiply and divide first, and then add and subtract, and 6 2 3 should be calculated from left to right.

It can be counted sequentially, 6 2 = 3, 3 3 = 9. It can also be taken as 6 3 2 = 9

If you don't have parentheses, you should do the division first!

Without parentheses, multiplication and division are calculated sequentially.

If there are parentheses, count the brackets first, and if there are no parentheses, multiply and divide first, then add or subtract.

There is addition, subtraction, multiplication and division to calculate addition and subtraction first, from left to right, without addition and subtraction without parentheses, it is also from left to right.

The same level of operation from left to right, multiplication and division belong to the same level of operation, so who counts who first counts whom, if there are parentheses, first calculate the parentheses, if there is a multiplication omitted multiplication, first calculate the multiplication, such as: 50 175*28 first calculate 50 175, then calculate multiplication, 500 10 first calculate 10, and then calculate division.

Count the curly braces {} first, then the middle brackets, then the parentheses (), and finally the rest of the parts, this is the operation rule.

Multiplication and division are in no particular order, e.g. 10 5 2 = 25 10 2 5 = 25

According to their precedence. If the division sign is in front of the multiplication sign, it is divided first and then multiplied, and vice versa.

This is the symbol of the same level: multiplication before the multiplication, division before the division.

There is no precedence.

For example, 100*10 5 multiplication is equal to 200, and division is also equal to 200

In order, the division sign is first divided and then multiplied, and vice versa, the multiplication sign is multiplied first and then divided.

In real number operations, multiplication and division are now added and subtracted, and multiplication and division are sibling operations. Under normal circumstances, count from left to right, if there are parentheses, count the brackets first.

Parenthesis operation priority.

First, second, and last

With or without parentheses, with or without the four operations, in no particular order.

If there are parentheses, count the brackets first, and if there are no brackets, count them in the order from left to right of the formula

Not in order, multiplication and division is actually a fractional operation.

Hello, multiplication and division are not in order, which is in front of which is calculated first, I hope it will be useful to you, welcome to ask.

There is no precedence between multiplication and division.

The algorithm is: bracket first, then square, then multiply and divide, and finally add and subtract.

Multiply and divide first, then add and subtract.

The result of multiplication or division is the same, so multiplication and division can be done in order.

Multiplication and division are of the same priority, step by step from left to right, if there are parentheses or something, count the parentheses first.

The one in parentheses is counted first, and the ones in parentheses are counted in parentheses first.

Multiplication and division come first, and whichever comes first.

The math problem is multiplied and then divided or self first.

In addition to multiplication, this bai is in no particular order, it depends on the follow.

duleft to right

Which one is in front of the first is counted as the dao first!

The general algorithm is: first calculate the brackets, then open the square, then multiply and divide, and finally add and subtract.

For example, 200 (3-2)*2=200 1*2=400 (ps: divides * is multiplication).

It doesn't matter, if there are parentheses, just count the parentheses first.

In the order of the formula from left to right.
