Use the sign of $>, <$ or $=$ in the box to make the statements true.
(a) $(-8)+(-4)\ \square\ (-8)-(-4)$
(b) $(-3)+7-(19)\ \square\ 15-8+(-9)$
(c) $23-41+11\ \square\ 23-41-11$
(d) $39+(-24)-(15)\ \square\ 36+(-52)-(-36)$
(e) $-231+79+51\ \square\ -399+159+81$
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) $-231+79+51\ \square\ -399+159+81$
$-152+51\ \square\ -240+81$
$-101 > -159$
