Question

680-2=(670+10)-2=670+(10-2)-670-8

Answer 1

Пошаговое объяснение:

680-2=678

(670+10)-2=678

670+(10-2)-670-8=0

Answer 2

Let's break down the expression step by step:

First, we have 680 - 2: 680 - 2 = 678

Next, we have (670 + 10) - 2: 670 + 10 = 680 680 - 2 = 678

Therefore, the first two parts of the equation are equal to 678.

Now, we have 670 + (10 - 2) - 670 - 8: 10 - 2 = 8 670 + 8 = 678 678 - 670 = 8 8 - 8 = 0

Therefore, the last two parts of the equation simplify to 0.

Putting it all together, we have: 680 - 2 = 678 = 670 + 10 - 2 = 670 + (10 - 2) - 670 - 8 = 0

So, the final result is 0.
