Answer 1

Пошаговое объяснение:

500-50×(2+3)=250

20+80:(4-2)=60

Answer 2

To make the expressions true, you need to add parentheses to change the order of operations. The correct arrangements of parentheses are as follows:

1. 500 - (50 × 2) + 3 = 250
2. (20 + (80 / 4)) - 2 = 60

Explanation:

1. In the first expression, we need to ensure that the multiplication is performed before the subtraction. By putting parentheses around (50 × 2), we make sure that this multiplication is done first, resulting in 500 - 100 + 3, which equals 400 + 3 = 250.

2. In the second expression, we need to ensure that the addition and division are performed before the subtraction. By putting parentheses around (80 / 4), we make sure that this division is done first, resulting in (20 + 20) - 2, which equals 40 - 2 = 60.
