Off-form calculation, solution idea: When doing this off-form calculation, you should first consider the calculation in parentheses. Then consider multiplication and division first, and then add and subtract.
Then when we do the specific calculations, we should consider the above calculation steps and calculate the answer step by step. Here you can calculate the division operation first, and then the subtraction operation, and you can get the answer.
The detailed calculation process is as follows.
92 and 2 15
So, through the above calculation process, the answer is 92 and 2 15.
Extended information: Fraction Reduction: If we look at whether a fraction is the simplest fraction, then we need to examine the numerator and denominator to see if they have only one common factor 1, which is a coprime relationship.
If it is, then it is the simplest fraction; If not, then the simplest fraction is obtained by reducing by short division.
Step 1: The common factor of 2 and 15 is only 1

Off-line calculations.
Solution: Four rules of operation (calculated in order, multiplication and division first, then addition and subtraction, parentheses are counted first, and power is calculated first), that is, the off-form operation (recursive equality calculation) needs to be carried out under the premise of this principle. Problem solving process:
92 and 4 5-2 3
92 and 12 15-10 15
92 and 2 15
Extended Data - Reduction Process: The basis for judging whether a fraction is the simplest fraction can be based on whether the common factor of the numerator and denominator is only 1, if there is only 1, the fraction is the simplest fraction, and vice versa; If the numerator and denominator are decimal, they can be rounded before being judged.
Problem solving: Because the common factor of the numerator and denominator is [1, 2, 4]8 12: the simplest fraction is 2 3
If you have any doubts, please ask and be satisfied.

Hello! I'm glad to answer your questions!
Just follow the normal steps to calculate the reverence).
Yours is the greatest support to me! Good luck to you! Thank you!

There's nothing to do with the simple calculations here.
Target. Obviously, it is 3 times that of wild talk.
That is, if you get it, then add the waiter to make trouble.
The result is:
-
Division first, then addition.
-
This problem is the best simple calculation according to the rules of operation.

First of all, the multiplication and bending method is calculated, which is equal to 1, and then the division, because a number is divided by 1, and the result is that it talks about the history itself, and finally calculates the subtraction.

Simple example of the imitation cavity calculation? Hello, if you look closely at this equation, you will find that the answer shirt appears twice, so start with this number and transform this equation to: .

This is actually the basic application of the multiplicative distributive law.
After the decimal point is moved.
You can get it.
So it is equal to. Of course, the result of a simple calculation is.
Math Easy Calculation Method:
1. Simple calculation using the multiplicative distributive law. >>>More
Analysis: This problem uses the commutative associative law of addition, and then calculates it after rounding. The steps are as follows: >>>More

Solution analysis: rounding, according to the four rules of operation for the operation, the same level of operation is calculated in order, and the different levels of operation are calculated first, so the result can be obtained quickly.
