Question

Evaluate: [(- 16) + 4] ÷ [(-2) + 5]

Answer 1

Our focus here will be on the figures inside () to start on with; considering these figures are - & + accordingly:-

( (-16) + 4 ) ÷ ( (-2) + 5 )
= (-16 + 4) ÷ (-2 + 5)
= (-12) ÷ (+3)
= -4

So, the answer is (-4)

Answer 2

We need to evaluate this: [(-16)+4] / [(-2)+5]

First, we do the brackets:

• [(-16)+4]
• [(-2)+5]

[(-16)+4] = -16 + 4 = -12

[(-2) + 5] = -2 + 5 = 3

Now, we only need to divide, as we have calculated both brackets:

-12/3 = -4

(Remember that when dividing a negative number by a positive one, we always obtain a negative)

So the result is -4
