Answer 1

Решение во вложении

Answer 2

Пошаговое объяснение:

(а-m)-(b+n) = a-m-b-n  

(a+m)-(b+m) =  a+m-b-m = a-b

(a-m)-(b-m) = a-m-b+m = a-b

Answer 3

Let's break down each expression and simplify them:

1. (a - m) - (b + n) = a - m - b - n = (a - b) - (m + n)

2. (a + m) - (b + m) = a + m - b - m = (a - b)

3. (a - m) - (b - m) = a - m - b + m = (a - b)

In all three cases, the final result simplifies to (a - b).
