Answer 1

${\purple{\underline{\underline{\mathtt{Answer}}}}}$

$\mathtt\orange{True}$

${\purple{\underline{\underline{\mathtt{Explaination}}}}}$

$\mathtt{Sum\:of\:positive\:integers\:always\:returns\:a\:positive\:integer}$

$\mathtt{Let\:a\:and\:b\:be\:two\:positive\:integers}$

$\bf{Then,}$

$\tt (\: x \: + \: y \: > \: x) \: and \: (x \: + \: y \: > \: y)$

$\bf{Hence,}$

$\mathtt{As\:x\:and\:y\:are\:positive\:and\:(x\:+\:y)\:is\:greater\:than\:them\:(x\:+\:y)\:is\:also\:positive}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\bf{For\:example,}$

$\bf{1.\:2\:+\:4\:=6,\:which\:is\:a\:positive\:integer}$

$\bf{1.\:127\:+\:322\:=449,\:which\:is\:again\:a\:positive\:integer}$

$\bf{Hence,}$

$\mathtt\pink{Sum\:of\:positive\:integers\:always\:returns\:a\:positive\:integer}$
