Answer 1

Ответ:

39 + 2  =41

390 + 20 =410

64 - 7 =57

640 - 70 =570

60 + 23 =83

560 + 23 =583

50 - 21 =29

750 - 21 =729

750 CM - 21 CM =729СМ

750 CM - 210 CM =540СМ

560 CM + 23 CM =583СМ

560 CM + 230 CM =790СМ

390 CM + 20 CM =410СМ

390 CM + 200 CM=590СМ

Answer 2

It seems like you've provided a mathematical expression with various terms involving both numbers and "CM" units. However, the expression is a bit difficult to interpret due to the formatting. If I understand correctly, you want to perform arithmetic operations on these numbers and units. Let's break it down step by step:

Given expression: 39 + 2390 + 2064 - 7640 - 7060 + 23560 + 2350 - 21750 - 21750 CM - 21 CM750 CM - 210 CM560 CM + 23 CM560 CM + 230 CM390 CM + 20 CM390 CM + 200 CM

I'll assume that "CM" is a unit or label that you've used, and I'll consider it as part of the numbers for now. Let's simplify the expression:

(39 + 2390 + 2064 - 7640 - 7060 + 23560 + 2350 - 21750 - 21750) CM - (21 + 750 + 210 + 560) CM + (23 + 560) CM + (230 + 390) CM + (20 + 200) CM

Now, performing the calculations for each set of terms:

1. (39 + 2390 + 2064 - 7640 - 7060 + 23560 + 2350 - 21750 - 21750) = -11857 CM
2. (21 + 750 + 210 + 560) = 1541 CM
3. (23 + 560) = 583 CM
4. (230 + 390) = 620 CM
5. (20 + 200) = 220 CM

So the simplified expression becomes:

-11857 CM - 1541 CM + 583 CM + 620 CM + 220 CM

Now, combining the terms:

-11857 CM - 1541 CM + 583 CM + 620 CM + 220 CM = -10475 CM

Therefore, the simplified result of the expression is -10475 CM. Keep in mind that if "CM" is meant to represent a unit of measurement, then this result would have the unit "CM" attached to it. If you intended something different, please provide more context or clarify the expression.
