Question

−(7,79−579)−(0,21−229)

Answer 1

Ответ:

800

Пошаговое объяснение:

1)579-7,79= -571,21

2)229-0,21= -228,79

-(-571,21)-(-228,79)= 571,21 +228,79=800

Answer 2

Let's simplify the expression step by step:

1. −(7,79−579) First, perform the operation inside the parentheses: 7 + (79 - 579) = 7 + (-500) = 7 - 500 = -493

2. −(0,21−229) Again, perform the operation inside the parentheses: 0 + (21 - 229) = 0 + (-208) = 0 - 208 = -208

Now, the expression becomes: -493 - (-208)

When you subtract a negative number, it is the same as adding the positive version of that number. So, we can rewrite the expression as:

-493 + 208

Now, perform the addition: -493 + 208 = -285

Therefore, the result of the expression is -285.
