How to easily calculate 4 03 7 8 5 97?

The whole formula is calculated first, and the first and third can be added to the whole for easy calculation.

Move items, the first and third are calculated first.

See screenshot for calculation.

Solution: In the equation, sum is a pair, which can be rounded, so it needs to be shifted, or it can be said to use the commutative law of addition associativity, put.

Add and then subtract , the columnar equation calculates:

So the result of this equation is .

This problem uses the method of calculation with symbols, which is actually the associative law of addition.

This is calculated with symbols).

Thank you!

Addition first, then subtraction. Original =

This problem can be used to perform a simple operation by the commutative property of addition and subtraction, i.e., the original formula =

The simple calculation is as follows:

You can easily calculate by changing the order of operations.

It can be calculated using the rounding method

Analysis: This problem can be easily calculated by commutative and associative properties.

It can be obtained according to the title, eleven 10 a.

It is calculated like this: first the addition and then the subtraction, i.e.

The simple algorithm is as follows, the original formula =(

Swap the order of operations. It is shown below.

Hope, thank you!

This question is calculated using the rounding method, so the answer is:

Add and then subtract to make up an integer.

So in the end, the answer is.

Swapping the position with sum + and then calculating it can make the calculation easy, i.e.:

How easy is the calculation?

Easy to calculate.

Analysis of the clever calculation process.

Solution: Four operations.

Rules (calculated in order, multiplication and division first and then addition and subtraction, with parentheses first with parentheses, with multiplication.

Calculate the power first) i.e. an off-form operation (recursive equation.

Calculation of annihilation) should be carried out on the premise of this principle. Problem solving process:

Extended Data $ Vertical Calculation - Calculation Result Modification: Align the subtraction with the subtracted unit, and then match the corresponding counting unit respectively.

The number on the subtraction, not enough to subtract the roll needs to borrow 1 from the high position, the result can be obtained by calculating in turn, the subtraction is less than the subtracted number, the two numbers will be swapped and subtracted, and the final result will be added with a negative sign; The decimal part is subtracted by referring to the integer subtraction step;

Problem solving: Step 1: Fractional part subtraction calculation.

Step 2: 0-0=0

Step 3: 1-0=1

According to the above calculation steps, the combined calculation result is as follows.

If you have any doubts, please ask and be satisfied.

Summary. Hello, the simple operation is the process of solving the problem: How to calculate the simple operation of = = = <>?

Hello, the simple luck of the prudent opening is the solution to the problem is too late too wide years: = = = <> but the teacher made a mistake in doing so.

Kiss. Then let's change the solution to the solution of the slippery formula = =3+ =3+7+ =10+ =10+ =

The calculation rules of decimal accompaniment addition and subtraction: 1To calculate decimal addition and subtraction, first align the decimal points of each number (i.e., the numbers on the same digits).

2.Then calculate according to the rules of integer addition and subtraction, and finally align the decimal point on the decimal point on the horizontal line in the number (there is 0 at the end of the decimal part of the number, and the 0 should generally be removed). Faith is <>

The details of calculating the : in an easy way are as follows:

Why can't this question be decoded, why doesn't it conform to the law of simple operation?

Summary. Calculate multiplication and division first, then add and subtract, how to calculate simple operations.

How to calculate simple calculations, this is not a simple calculation!

Multiply and divide first, then add and subtract, if you still have time, please give me a thumbs up! Thank you! I wish you all the best! Succeed in your studies!
