Answer 2

Answer:

-78

Step-by-step explanation:

(-30) + (-60) + (-18) + (30)

We know that,

(+)(-) = (-)

(-)(+) = (-)

(+)(+) = (+)

(-)(-) = (+)

By applying this rule on the given statement we get

→ - 30 - 60 - 18 + 30

→ - (30 + 60 + 18) + 30

→ - (108) + 30

→ - 108 + 30

→ - 78

Hence, the required answer is (-78).
