There are $2$ $2$ terms

Explanation:

There are $2$ $2$ terms.

Terms are separated by plus and minus signs unless the signs are
- in a bracket
- in a fraction
- under a root

$5 (- 4 a + 8 b + 7 c) - 3 (5 b - 11 c - 32)$ $color(red)(5(-4a+8b+7c)) color(blue)(-3(5b-11c-32))$

If the brackets are multiplied out we get $6$ $6$ terms.

$= - 20 a + 40 b + 35 c - 15 b + 33 c + 96$ $=color(green)(-20a)color(magenta)(+40b) color(lime)(+35c) color(magenta)(-15b) color(lime)(+33c) color(purple)(+96)$

If the like terms are added, we get $4$ $4$ terms

$= - 20 a + 25 b + 68 c + 96$ $=color(green)(-20a) color(magenta)(+25b) color(lime)(+68c) color(purple)(+96)$
