There are $2$ terms

There are $2$ terms.

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

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

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

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

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

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