Answer 1

$\huge\underbrace{\mathtt\red{S} \mathtt\red{O} \mathtt\purple{L} \mathtt\blue{U} \mathtt\green{T} \mathtt\pink{I}\mathtt\blue{O} \mathtt\orange{N}}$

$= + 18ab + ( - 5ab) + ( + 12ab)$

$= 18ab - 5ab + 12ab$

$= 13ab + 12ab$

$= 25ab$

Answer:

$\huge \bf \: question$

sum of +18ab, -5ab, +12ab

$\huge\orange{\boxed{\purple{\mathbb{\overbrace{\underbrace{\fcolorbox{orange}{aqua}{\underline{\red{Solution}}}}}}}}}$

$+ 18 \: ab \: - 5ab \: + 12 \: ab$

$18ab \: + 12ab \: - 5ab$

$30ab \: - 5ab$

$25ab$

$\huge \fbox {sum \: = 25ab}$
