I also wrote it for your reference:

First, write about the difficulties you have encountered in your life.

Then write how you explore and solve problems.

Then write a simple ending

Anyway, that's what I wrote

I'm in grade six, too.

I wrote a simple calculation.

For example (I wrote this):

Simple method calculation

Every exam, we basically have to get the calculation done. Students must be tired of calculation, especially elementary arithmetic, plus fractions and decimals, which is really annoying. However, after all, the exam is to get the calculation, so how to make the calculation less annoying and less prone to mistakes? Then use the law of simple calculation.

The common laws of simple calculation are: additive commutative law a+b=b+a, and additive combination law a+b+c=a+(b+c).

For example, the following problem appeared in our three trainings: 0.88× 100 438+0.

If this topic is calculated vertically, it will be very troublesome and may be miscalculated. If you want to do a simple calculation, you can divide 100. 1 into 100+0. 1, and then do a simple calculation with the multiplication distribution law:

0.88× 100. 1

=0.88×( 100+0. 1)

=0.88× 100+0.88×0. 1

=88+0.088

=88.088

In this way, the calculation is much simpler, and there is no need to die and it is not easy to make mistakes.

Although formulas can be used in calculation, some problems need to be calculated step by step. For example, there are two groups of four operations that are easily fooled: 12×48÷ 12×48 and 12×48÷( 12×48). The first one looks like it can be worked out quickly. It's actually just a trap. If you have to do a simple calculation for the first one, you can also use 12 and ÷ 12 to offset and convert it into 48×48. The second operation sequence is opposite to the first one. Calculate 12×48 in brackets first, and then calculate the previous 12×48 according to the operation order, which can be converted into 1÷ 1, and the result is equal to 1.

It's hard to calculate and see. In fact, just use some algorithms, just like a magician, to make the calculation simple. So, mathematics is wonderful. As long as you study hard and think hard, even the most difficult math problems will be solved. I wish you progress in your study! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
