Answer 1

$\Large\boxed{\begin{array}{l}\tt a)\\\sf(2+3i)+(5+7i)=\underline{7+10i}\\\tt\!\!~\sf b)(3+4i)-(9-2i)=\underline{-6+6i}\\\tt c)~\sf(-2-3i)+(5-2i)=\underline{3-5i}\\\tt d)~\sf2-(5-2i)=\underline{-3+2i}\\\tt e)~\sf(5-3i)+4=\underline{9-3i}\end{array}}$

$\Large\boxed{\begin{array}{l}\tt f)~\sf(7+2i)-5i=\underline{7+7i}\\\tt g)~\sf(8-3i)+(-3+2i)=\underline{5-i}\\\tt h)~\sf(9i+3)-(2-3i)+4i=\underline{1+16i}\\\tt i)~\sf(7i-2i)-(3i+2)-5=\underline{-7+2i}\\\tt j)~\sf(2+3i)-4i+(7-3i)=\underline{9-4i}\end{array}}$

$\huge\boxed{\boxed{\boxed{\boxed{\red{\maltese}~\blue{\mathbb{D}\mathbb{E}\mathbb{U}\mathbb{S}~\mathbb{V}\mathbb{U}\mathbb{L}\mathbb{T}}}}}}$
