Answer 1

Answer:

The first, second and fourth expression has a value less than -3.

Step-by-step explanation:

First, solve all of them.

i)$- 1 + ( - 5) + 2 \\ = - 1 - 5 + 2 \\ = - 6 + 2 \\ = - 4$

ii)

$4 + ( - 9) \\ = 4 - 9 \\ = - 5$

iii)

$- 10 + 8 = - 2$

iv)

$3 + ( - 8) + 1 \\ = 4 + ( - 8) \\ = 4 - 8 \\ = - 4$
