How to do the easy way to 9 6 57 430 0 96?

In this problem, we will first multiply the sum and then extract the common factor.

Simple calculations using the associative law of multiplication.

Hello! I'm happy to answer your questions, and here's what I've got for you:

How to calculate it in an easy way?

Answer: Convert to, so that you can extract the common factor calculation, and implement the easy way: original formula=

How to calculate it in an easy way?

Answer: Convert to, so that you can extract the common factor calculation, and implement the easy way: original formula=

You can use the distributive property of multiplication to make a simple calculation, but first you need to use the properties of multiplication to change 430 to 43. Original

First of all, convert the latter to, so that the sum of these two multiplication formulas has a common factor that can be extracted, and the common factor parentheses are extracted, and the sum of 57 and 43 is left, and this sum is exactly an integer 100, so the answer 960 is quickly obtained.

Simple calculations are obtained by extracting the common divisor directly.

96x100

The calculation process is as follows:(Written.)

10 Multiplying two numbers by the same number is equal to multiplying two minus numbers by the same number) 250-5 (subtracting the two products).

245 (the result is the same as the result obtained if the calculation is not simplified).

Multiplication Properties:Multiply the product of several numbers by a number, so that any factor in the product can be multiplied by this number, and then multiplied by other numbers. For example:

Multiplying the difference between two numbers by one number allows the subtracted number and the subtracted number to be multiplied by this number, and then the resulting product is subtracted. For example: (137-125) 8=137 8-125 8=96.

。Amount.

In fact, Lingzheng you are like 25 4=100, which is what most people know. However, after the simple annihilation, you can just be able to stop Wang Chong enough, uh, there is a four.

The simple calculation method of this knowledge paragraph is to make up the whole before the calculation. Split 8, and then use the commutative law to calculate 8 25 first

Because, so the original equation is equal to 4, using multiplicative slip or tie the letter potato law.

Changing the order of the group and counting the information does not change, so it is.

Using the law of multiplication and associativity, it is easy to carry socks and carry good luck, and it is stupid.

Because, while.

Then the simple way of the original formula is to be sensitive. Cautious.

Seeing this sock cover, I often use the completion method to become, and then use the multiplication distribution law to calculate Biqing.

Simple AlgorithmThe simple algorithm is to change it to a fraction, and then 10 can be booked with 25, and it is convenient to calculate after the appointment.

(Question.) Thank you, teacher.

You're welcome.

Then the line or Sun Yu will be written as a fraction with 25 about the destruction of the slippery score.

98/10x25＝490/2＝245

Hello, this can be seen as (

The easy way to calculate:

This formula contains a distributive property that can be split into and then multiplied.

The answer is 4. You can make the ruler multiply by 5 to get 48, and then use 48 12 to get the answer 4.

(10 minus beats multiplied by 23.)

10 minus multiplied by 23 equals 230 minus equals.

First, find the product according to the rules of integer multiplication. If you look at how many decimal places there are in the multiplied number and the multiplier, count the number from the right side of the product and point to the decimal point. If there is a 0 at the end of the decimal, according to the basic nature of the decimal, the 0 at the end of the decimal is crossed out.
