How to make the number in one table equal to the formula in another in Excel, for example, I input 2 + 3 in one column and directly output 5 in another column?

There are two ways I can solve your problem

① 35% of a number is equal to 1 / 5 of 70. What is the number
② The difference between 3.2 times of a number and 60% of this number is 7 and 4 / 5. How much is this number
③ What is the sum of 1 / 6 of 1 plus 20% divided by 8

① 70 × 1 / 5 △ 35% = 40
② 39 / 5 (3.2-60%) = 3
③ 1 × 1 / 6 + 8 △ 20% = 40 and 1 / 6 = 241 / 6

What number's Square equals - 1 (minus one)
Is there any RT that I don't know? If so, can you tell me why?

The square of imaginary number I is equal to - 1
Definition I = root - 1
Since the square of a negative number will be negative and positive, the result will be positive. Then people think, what number does not follow the principle of negative and positive? Then this number is not a real number, it is a false number, so we call it an imaginary number. An important concept in the imaginary number is I. defining I = root - 1 is the basic condition for creating an imaginary number, I can't be mixed with a real number unless it is squared and becomes - 1, which is a real number

80% of 50 is equal to 5 / 8 of a number?
Write down how you got the number,

Let this number be X
50*80%=5/8X
5/8X=40
X=64

Three times of a number plus this number is generally equal to 80.5. Find this number, three times of a number plus this number

80.5/(3+1/2)=80.5/3.5=23
So the number is 23

8 minus 13 and one in two equals? 0 minus 5.5 minus 8 and one in two minus 7 and one in two equals?
6.13 minus 10.13 minus 13 out of 10
One in two minus three in four minus one in four plus five minus one in two equals

8 minus 13 and 1 / 2
=-5 and 1 / 2
0 minus 5.5 minus 8 and 1 / 2 minus 7 and 1 / 2
=0-5.5+8.5-7.5
=-4,5
6.13 minus 10.13 minus 13 / 10
=6.13-10.13+1.3
=-4+1.3
=-2.7
