How to calculate the simple calculation The simple calculation is so calculated;

The result of this question is: When we do this problem, we can think of it as if we use the multiplicative distributive property to do the calculation. This will make the calculation easy. But be sure to put it in parentheses.

If you are simple to calculate at 2:5 0:99, you can make it 1-0:01

2.5 0.99=2.5 1-2.5 0.01=2.5-0.025=2.475

Hello, happy with your question. Original =

Here it can be divided into four multiplied by, four, multiplied by exactly equal ten, and then multiplied to get the correct answer.

With the simple calculation of the early forward square cavity opening belt type is different from 4, so it can be seen as 4-0.01

Therefore, the original formula is equal to 2.5 4-2.5 0.01=

It should be turned into 4 minus.

You turn the equation into a brother's destruction.

This makes it easier to calculate. The Companion Dust makes use of the multiplicative distributive law of Lusan.

, calculated by the simple stool method, pure leather can be calculated in this way.

It would be correct to say that just to destroy the errand.

The process of accompanying the simple fortune is as follows: stupid.

Easy to calculate.

Simple calculation idea: If we do simple calculation, we can use the distributive property of multiplication operation or the properties and laws of associative law or division operation to calculate, and get the effect of our simple calculation. If you want to do a simple calculation here, you can try to convert it to and then use the distributive property of multiplication to calculate, which will be easier.

The detailed and simple calculation process is as follows.

So, here you can get the answer from the simple calculation process above.

Calculation: Solution: When we calculate the division operation, try to choose that both the dividend and the divisor are integers.

If there is a decimal between the dividend and the divisor, it can be calculated as an integer. When calculating, you should start from the high position of the dividend, divide the divider in turn, get the quotient, keep the remainder, and then calculate the next step. If it is an infinite loop decimal place, it can be calculated to a few decimal places as required.

Step 1: 2772 990 = 2, remaining 792

Step 2: 7920 990 = 8

Therefore, it can be checked by the division operation of vertical calculation, and the answer is yes.

This question can be morphed into:

1. In order to obtain good academic performance, it is necessary to firmly grasp the four basic links of preview, listening, homework and review. Among them, the pre-class preview textbook can help students understand the key points and key points of new knowledge, and find difficulties, so that they can focus on solving them in the classroom, grasp the initiative of listening to the class, and make the lecture targeted. As the grade level increases, the importance of preparation becomes more prominent;

2. Cultivating students' ability and habit of inspection is an important measure to improve the quality of mathematics learning, and it is a necessary process to cultivate students' consciousness and sense of responsibility.

3. Mathematics is actually abstract, and primary school students' thinking is concrete, even in the process of teaching. Teachers also ask students to use their hands and brains at the same time, and solve difficult concepts by giving examples. For the fuzzy geometric knowledge, the purpose of throwing stones and asking for directions can be achieved through cutting, cutting, patching or experiments.

0 You have to exercise every day. Without a healthy body, you can't do anything, and even if you do it once in a while, it won't last long. About 30 minutes of exercise every day must be insisted on every day.

There are many forms of exercise, running, table tennis, basketball, push-ups, standing long jump, and so on. Some students have a good face, and when they see others not running, they are afraid that they will be embarrassed when they run and others will see it, then they are wrong, and what is really embarrassing is that they can't get into college after a few years of hard work, and they have to be laid off after a few years of college. If you can't support yourself, that's what you're really embarrassed about.
