Easy to calculate.

Here's how it works: So the final result of a simple calculation is 5560.

That's 100, and the common factor is extracted.

Easy to calculate.

Calculation steps:

1.When you first see this problem, you will find that the addition of the deciles of two numbers is exactly equal to an integer, and the same is true for subtraction.

2.So we can use the associative and commutative properties to put addition together and subtraction together. You can get it. This simplifies our calculations and makes them more accurate and fast.

Associative Law:The associative law of addition and subtraction refers to the addition or subtraction of three numbers, adding the first two numbers first, or adding the last two numbers first, and not changing late.

Commutative Law: The commutative law of addition and subtraction is the first of the laws of mathematical calculation. It refers to the addition of two additions, the exchange of the lead position of the addition, and the unchanged.

Commutative property is a property of binary operations, which means that in a representation containing more than two commutative operators, as long as the operators do not change, the order of operations will not affect the calculated value.

Simply swap the position, the front of the shirt is equal to the collapse of the positive 50. The result is 100 minus 50 and so on 50

Using the additive exchange rate, and the additive binding rate, (a(50.)

Simple calculations, I can exchange the position of the hand clap of the addition and subtraction

Solution: It can be calculated by using the commutative law and the associative law of the commutative method. Add the same first, and then guess the sum of the companions. Spike stupid calculation process.

Sakura replied: Zhao quietly waited for the spine to be in an uproar.

Convert it to, so that the multiplier of the two additions becomes the same, and then use the gesture multiplication method to assign the law of annihilation to change the calculation:

The knowledge points used in this question: (1) The two factors are multiplied by the same stool, one is expanded by n times, and the other factor is reduced by n times, and the product remains unchanged. (2) Do the inverse operation of the distributive law of number multiplication. Solution:

Pure macro first 10).

Swap the latter one with one and apply the multiplicative distributive property.

According to the simple calculation of the embedded code of the mold silver problem, it can be calculated in this way. Curved bridges.

How to write a simple calculation.

Summary. The simple calculation.

Hello, wait a minute.

The simple calculation. Just leave the brackets out.

The answer is equal to 40
