Question

8. Simplify each of the following:
(a) -55 - (-33-22)
(b) (-103 + 93) - (35 - 108)
(c)(-15-13) + (18 - 10)
(d) (-28 - 11) + (-19-17)​

Answer 1

$a) - 55 - ( - 33 - 22) \\ = - 55 - ( - 55) \\ = - 55 + 55 \\ = 0$

$b)( - 103 + 93) - ( 35 - 108) \\ = - 10 - ( - 73) \\ = - 10 + 73 \\ = 63$

$c)( - 15 - 13) + (18 - 10) \\ = - 28 + 8 \\ = - 20$

$d)( - 28 - 11) + ( - 19 - 17) \\ = - 39 + ( - 36) \\ = - 39 - 36 \\ = - 75$
