Раскрой скобки (2-3)-(3-8)(7+7)

(2-3)-(3-8)(7+7) First, we evaluate the expression inside the parentheses: (2-3) = -1 (3-8) = -5 (7+7) = 14

Now, we substitute the values back into the original expression:

(-1) - (-5)(14)

To simplify, we multiply -5 by 14:

(-1) - (-70)

To subtract a negative number, we change it to addition:

(-1) + 70

Finally, we add the numbers:
