67 Add 15 and subtract 20 from 67, how much do you get?

The recursive equation calculates 67+15-20

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:

Extended data - vertical calculation - calculation results: align the subtraction with the subtracted number of single digits, and then subtract them respectively with the number on the corresponding counting unit, if it is not enough to subtract, you need to borrow 1 from the high position, and calculate the result in turn, the subtraction is less than the subtracted number, and the final result of the two numbers will be exchanged and subtracted by adding a negative sign; The decimal part is subtracted by referring to the integer subtraction step;

Problem solving: Step 1: 2-0=2

Step 2: 8-2=6

According to the above calculation steps, the combined calculation result is 62

If you have any doubts, please ask and be satisfied.

67 + 15 = 82, 82-20 = 62, so 67 first add 15, then subtract 20, and get 62.

First 67+15 equals 82, 82 and then -20 equals 62. So the final result is 62.

According to the proposition column, it is calculated as.

So the answer is 62

67 Add 15 and subtract 20 from 67, how much do you get?

67 first add 15, and then subtract 20 to get 62, the calculation process is 67 +15 -20 = 82 - 20 = 62

67 first add 15 to the difference, and then subtract 20, that is.

67 + 15 = 82, 82-20 = 62, so 67 first add 15, and then subtract 20 from the branch to get Lao Jinmin 62.

Then we can calculate it by two vertical calculations, one of which is 27+15 is equal to 42, and the other is 63-42.

Summary. Dear, have you learned negative numbers? This is a negative number.

Look at your question for any mistakes.

67 how much ten minus 20 two 10

Dear, have you learned negative numbers? This is a negative number. Look at your question for any mistakes.

You see, it's 67 ten, how much is 20=10

That's -37. Negative 37. If you haven't learned negative numbers yet, there's something wrong with the problem.

This number is 41

You can use the method of backwards to know that the final answer is 50, first calculate the second half of the backwards is 50-26 24, and then calculate the first half of the backwards is 24 + 17 41, the final answer we can add to the formula to check whether it is correct, then 41-17 + 26 is equal to 50. After the calculation, the final answer was 41.

Let this number be x, then x-17+26=50, x=41, so this number is 41.

Let this unknown be x

x-17+26=50

x=50-26+17

x=41 then the number is 41

The calculation method of this problem is as follows: first use 50-26=24, then use 24+17=41, so that this number is equal to 41.

This problem can use the law of subtraction and subtraction to get this number, that is, 50-26+17-41, and this number is 41

Solution: Let this number be x

x-17+26=50，x=41。

A: The number is 41.

Suppose this number is a

Then a 17 + 26 = 50

then a = 50 26 + 17

So the number is 41

Understanding 1: (61+x)-17=25

Solving the equation yields: 61 + x = 25 + 17 gives x = -19 comprehension 2: 61 + (x - 17) = 25

The solution shows that x=-19

Summary. This question is up to me, it takes a little time to type, so please be patient.

Subtract 26 from a number, subtract 18, and add 37 to equal 60. What is this number?

This question is up to me, it takes a little time to type, so please be patient.

Hello waiter The answer is 67 Assuming the number x is the old Zhao clan x 26 18 + 37 upside down: 60 37 + 18 + 26 = 67

Summary. 62 minus how much is equal to what is plus 40

Dear, it's written according to your requirements.

62 minus 2 equals 60, and adding 40 equals 100
