657 198 How simple is it to calculate?

657 198, if this problem is a simple calculation, it should be carried out using the rounding method, first use 657-200+2, and then the calculation result is 457+2=459, and finally you can get the answer to this question is 459.

657 198=657 198 2+2=657 (198+2)+2=657 200+2=Four hundred and fifty-seven plus two equals four hundred and fifty-nine.

That's it for the easy calculation.

Think of 198 as 200-2 so I can get 657-200-2 457-2 455, so it's easy to do the math.

You can use 657 pages, subtract 200, and then add 2 to get 459. That's the easy way.

And look at this more carefully: Reading any good book is like talking to the most brilliant people of the past. With these questions in mind, let's examine attitudes. With these questions in mind, let's examine attitudes. I have to work hard under all kinds of pressure.

This type of problem can be calculated by rounding the original formula = 657 - (200-2) = 657 - 200 + 2 = 459

The simple operation of 657-198 is 48, 198 becomes 200-2, and the result is that the problem is equal to 657-200, and then subtract two, and the receiving is equal to 457-2, which is equal to 455

This converts 198 to 200-2, which is 657-200+2 459

The simple solution to this subtraction problem is to round 198 to 200-2. In this way, using 657-200 first equals 457, and adding 2 equals 459. Because after subtraction opens the parentheses, it becomes addition.

A simple calculation is as follows.

Hope it helps.

The 657-198 easy method is as follows:

The answer is 459

657297 can be seen as the addition and subtraction of an integer, and the result can be calculated by adding and subtracting with addition and subtraction or subtraction. That is to say, 657-297 = 650-300 + 7-7 = 350

You can add or subtract 657297 to an integer, then add or subtract multiple or fewer numbers, and then calculate the result. That is, 657-297 = 650-300 + 7-7 = 350

657297 can be added and subtracted as integers. After addition and subtraction, the numbers can be added or subtracted, and the lead can be rented and the result can be calculated. That is, 657-297 = 650-300 + 7-7 = 350

Convert 298 to 300-2, that is, 657-(300-2)=657-300+2=357+2=359, and the answer is 359

The simple arithmetic of 459-197 can be matched with the line to talk about this with the selling of the front sample.

This question uses the method of making up a hundred methods, 197 is regarded as this branch 200-3, remember to envy the brackets Senpaimin, and then remember to change the number when going to the brackets.

Here's how to do it:

459-(Xiang Sell 200-3).

262。Sleepy celebration.

Four hundred and fifty-nine minus one hundred and ninety-seven equals four hundred and sixty-two.

Change 197 to (200-3), and then calculate the simple judgment according to the mixed operation algorithm of adding Zheng and subtracting. Namely:

459-197

459 A (200 A 3).

459 a command with 200 ten 3259 ten 3

459 minus 197 is easy to calculate, and I think it's okay to be simple here. If 197 is regarded as 200-3, then this question becomes 459-200+3, which is equal to 259+3, which is equal to 262.

It can be calculated after transformation, 459-197 = 459-200 + 3 = 259-3 = 256, so the answer is 256

Because e.g., 197=200-3, the original liter rubber width is 459-(200-3) and the addition and subtraction algorithm is 459-200+3=259+3=262

The process of simple calculation of the spine circle is shown in the defeat of the lower limbs

This is a good calculation, directly subtract 200 from 459 to equal 259, and then add 3 to equal 262

You can think of the subtraction as 200 minus 3, then subtract 200 from 459 to get or eliminate the omen to 259, and then add 3 with 259 to get the answer 262. Shirt rental.

A simple calculation of 459 197 does so:

Convert to Senhu's nearest whole 100 liquid spring liquid first.

Such as 400+59-200+3

Thank you.

You can first treat 657,297 as integers for addition and subtraction, and then subtract the additional or subtracted numbers after adding and subtracting, and the result can be calculated. That is, 657-297 = 650-300 + 7-7 = 350

Solve this problem by matching whole numbers.

Summary. 657-298 is calculated using the easy method.

Can you elaborate on that a little bit more?

First, make up 298 (300-2), remove the brackets, and continue.

Summary. 657-298 for easy calculations.

Can you elaborate on that a little bit more?

In this question, we can think of 298 as an integer hundred 300, and if we subtract 2 from that, we have to add 2

How to calculate 657 + 198 + 723-297 simply, is it possible to list like this:
