Easy Calculation Solution 20, Simple Calculation Solution

<> directly convert 24 into fractions for approximation, and finally multiply 32 by 16 to perform simple calculations.

Isn't this the covenant?

32 and 24 make an appointment with an 8, and there are 3 left below, and then go to 384 to make an appointment, so be it.

Hello subject! Original = 32 * 384 24 = 32 * 384 (8 * 3) = 32 8 * 384 3 = 4 * 128 = 4 * (130-2) = 520-8 = 512, I hope to help you solve the problem.

In my opinion, the numbers in this problem have a multiple relationship, and it is appropriate to use the method of mentioning the common factor. Original = 4 8 [4 8 12 (8 + 16)]=4 8 [4 8 12 (3 8)]=4 8 4 8 4=4 8 =64 =3600+2 240+16=4096. Personal opinion, for reference only.

The whole formula can be equal to 32*384 24=4*384 3=4*128=512, and the common divisor is removed, so that the calculation is relatively simple.

Count the inside of the parentheses first, then the inside of the middle brackets, and then remove the brackets, to get 32 16, and the final answer is 512

According to the four rules of operation, first multiply and divide and then add and subtract, first calculate the brackets, and then count the outside of the brackets, and calculate from left to the right of the trembling car. Yard slow.

First find the parentheses to brighten the multiplication of the spring Jingnai =

。First, the decimal point is shifted to the same number of digits, and then the inverse operation of the multiplication distribution rate is used to perform a simple operation, and the final Sun Fan knot is 456, and the other problems are the same.

**There are more songs in the title, but it seems to be multiplication, and the simple Yunye in multiplication is mainly to learn how to use 4 * 25 = 100, 8 * 125 = 1000 and related deformations.

For example, in this question, pay attention to it, then you can find a way to convert it into 8 or multiples, because 8*125=1000, so the form of the formation is better calculated. So.

Grade 5 decimal simple operation can refer to the method of integer simple operation.

These are some of the most basic questions, why not? What are you doing if you didn't pay attention in class? Don't waste your time.

It is possible to swap the order calculations.
