398A 198 Ten 129 How to calculate it simply?

Hello this friend. This is an easy way to remove the small brackets. Then it's 398-198-119. We easily get 200-119. The end result was 81.

The simple algorithm is actually to open the brackets, 398 first minus 198, and then subtract 129.

This single calculation problem is actually very simple, first remove the brackets, and then subtract it.

Hello, remove the brackets from the calculation, i.e. 398-198-129 = 200-129 = 71

You can write it as 398-198 and subtract 129. In this way, it is equal to 200-129=71, which is simple.

Calculate that 398-198 is equal to 200 first, and then use 200-129=71, so the final result is 71.

In fact, you can calculate the sum of 398-198 plus 129 in this simple operation, in fact, you can remove the deduction number first, g is 398-198 + minus 129, so that it can be calculated in a simple way.

Hello, you can go directly to the parentheses and become 398 minus 198 minus 129 equals 200 minus 129 equals 71

If you want to do the simplest, just remove the parentheses, 398-198=200, and subtract 129 to equal 71

This must be open the brackets, that is, 398-198-129, then 398-198 will get 200, 200-129 will get 71!

398-brackets 198+129 How to decompose it, just open the brackets and calculate it, and there is no order.

The simple operation of this problem is to open the brackets.

Finish 398-198 in parentheses, and add 129 at the end.

This is one of the simplest algorithms for addition and subtraction, and you have to be able to swear by this simple algorithm before you can calculate this equation. It's a very simple math problem.

Like this, I think this simple algorithm is very easy, you can use 398-198 and then add 129.

The simple operation is to take out the parentheses. Calculate them one by one.

It's good to add and then subtract first.

That's it, even if it's still very simple, you need to calculate the answer to the deduction number first, and then subtract it with 398.

If you do the simple calculation, just split the 398.

This question can be easier by removing the brackets first.

Simple algorithm: 398 a (198 ten 129).

398-198-129

200-129

This algorithm should be very simple, first subtract 198 from 398 to equal 200, and then subtract 129 from 200 to equal 71. In the process of learning mathematics, being good at solving problems with simple methods can greatly improve your learning efficiency, save time, and increase your confidence in learning mathematics. Mathematics is a discipline that pays attention to methods, and sometimes there are many ways to solve problems, the key is to see how you use it, and it is also a very flexible subject.

99 98 + 198, this formula does have a simple algorithm, first of all, we observe the three numbers in the formula, where 99 and 100 are 1 different, so according to the distribution rate of multiplication, you can transform the above formula into (100-1) 98 + 198 = 9800-98 + 198 = 9900, and the associative property of addition and subtraction is used later in this formula.

After continuous transformation, the calculation is much easier.

About this equation 99 98 + 198 use a simple method to calculate, the process is as follows:

The back becomes 98+100

So (99+1) 98+100

Equal to 9800 + 100 = 9900.

The 402x99-198 Jianzhou celery chop method is as follows:

402x99-198 = (400 + 2) x 99-198 = 400x99 + 2x99-198 = 400x (100-1) + (2x99-198) = 400x100-400x1 =

Solving. Original tremor = 1996

Problem solving analysis. The number of disturbed vacancies in the slow hole blind formula is 8, and the application of the rounding method considers 1500-2 and 500-2, and then calculates.

Hello! Glad you raised your question! 198 + 203 + 98 + 399 Concise Answer Portable Computing:

198 2) (1 399) 200 Jingfu 98

Yours is the greatest support to me! Break a leg! Thank you!

203 split into 200 and 3, 3 split into 1 and 2, 1 and 399 plus 400, 2 and 198 or 98 plus.

The simple calculation process is as follows.
