57 101 57 How should I calculate it in the easy way?

The common factor in this problem is "57", so the original formula = 57x101-57x1 = 57x(101-1) = 57x100 = 5700

Dear, when you see this question, click in. Dear, this math problem is not very rare, it is a relatively common simple operation problem, carefully observe the problem you will find that there are 57 before and after, extract it, and calculate the rest together, you will be a guest, the specific solution process is as follows: 57 101 57 57 (101 1) = 57 100 = 5700.

The minus 57 can be seen as 57*1, so it can be simple.

The same type of question can be inferred.

Hello, the easy calculation process for this question is as follows:

57 101 57 How should I calculate it in the easy way?

Hopefully, thank you

The simple calculation is to directly extract the common divisor 57.

57x(101-1)

57x100

Calculations are made using the multiplicative distributive property.

57x101-57

57x（101-1）

57x100

57 101 57 How should I calculate it in the easy way?

57 101-57 is calculated as 5700 by the simple method.

Solution: 57 101-57

57x101-57x1

57x(101-1)

57x100

i.e. 57 101-57 is equal to 5700.

Extended information: 1. Associative law of addition.

The additive associative law is (a+b)+c=a+(b+c).

For example, 8+1+9=8+(1+9)=8+10=182, the commutative law of addition.

a+c=c+a。

For example, 8+5=5+8=13.

3. Multiplication and associative law.

axb)xc=ax(bxc)。

For example. 4. Multiplicative distributive law.

a+b)xc=axc+bxc。

57×101-57

This is the inverse of the multiplicative distributive property.

This makes the calculation easier.

Hello, you can use the multiplicative distributive property to calculate it simply, the original equation can be simplified to 57 (101-1)=57 100, and the result can be 5700 by the simple method.

This is very simple, because there is a common 57, this common factor extracts the common factor of 57 to the front, and then 101-1 appears in the parentheses at the back. Isn't this bracket equal to 100? Finally, 57 100 = 5700.

The common factor in this problem is "57", so the original formula = 57x101-57x1 = 57x(101-1) = 57x100 = 5700

The simple method is to use the multiplicative distributive property for calculations.

Here's how to do it:

Original = 57 (101-1) = 5700

The answer is 5700

57 19+57 simple arithmetic.

The application of the multiplicative distributive property can be used to make the calculation easy.

Extended Information: Multiplicative Distributive Property:

Adding (or subtracting) two numbers and multiplying another number is equivalent to multiplying the number by two additions (subtractions) respectively, and then adding (subtracting) the two products to give the same number.

Indicated by letters:

a+b）× c=a×c+b×c

Variant: (a-b) c=a c-b c

If we look closely at the problem, we will see that 57 appears twice, so just extract this common factor, and you're good to go.

This problem uses multiplication to distribute the rate.

Think of 57 as 57x1

According to ab+ac=a(b+c).

Get 57x19+57x1

57x（19+1）

57x20

This problem uses the multiplicative distributive property.

57x19+57

57x（19+1）

57x20

57 43+57 56+57 Extract a total of 57, easy to calculate.

See screenshot for calculation.

Bringing 57 out is (43+56+1)*57=100*57=5700, so it's simple.

A simple calculation of 57x43 57x56 57 is as follows: i.e. 57x(43x561) 57x100 5700

It is directly 57 times (43 + 56 + 1) = 57 times 100 = 5700.

By looking at the above equation, we can see that each term contains 57, so we can use multiplication to perform a simple calculation of the associative property of addition as follows:

According to the above question type, we can know that there are 3 57s, and one of them is subtraction, so you can use the multiplicative associativity to calculate, 57 18+57 83-57

57x (18 ten 83 a 1).

Hope you can adopt, thanks!

Analysis of the process of clever calculations 99 57 + 57

Solution: Four rules of operation (calculated in order, multiplication and division first, then addition and subtraction, parentheses are counted first, and power is calculated first), that is, the off-form operation (recursive equality calculation) needs to be carried out under the premise of this principle. Problem solving process:

Extended data $ vertical calculation - calculation process: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier for each digit from the last digit in turn, and finally add up the calculated result as the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiple, and finally the product is reduced by the corresponding multiple;

Problem solving process: Step 1: 7 99=693

Step 2: 5 99 = 4950

According to the above calculations, the sum is 5643
