To do:

We have to use the sign of $>, <$ or $=$ in the box to make the given statements true.

Solution:

(a) $(-8)+(-4)\ \square\ (-8)-(-4)$

$-8-4\ \square\ -8+4$

$-12\ \square\ -4$

$-12 < -4$

(b) $(-3)+7-(19)\ \square\ 15-8+(-9)$

$-3+7-19\ \square\ 15-8-19$

$-15\ \square\ -12$

$-15 < -12$

(c) $23-41+11\ \square\ 23-41-11$

$-18+11\ \square\ -18-11$

$-7 > -29$

(d) $39+(-24)-(15)\ \square\ 36+(-52)-(-36)$

$39-24-15\ \square\ 36-52+36$

$15-15\ \square\ -16+36$

$0 < 20$

(e) $-231+79+51\ \square\ -399+159+81$

$-152+51\ \square\ -240+81$

$-101 > -159$
