Answer 1

-35

Explanation:

Answer 2

-35

Explanation:

I don't know what you are talking about but this is my method ;

`-20 + - 15`

It is best written as;

`-20+(-15)\\\mathrm{Remove\:parentheses}:+* - = -\\-20-15`

Note ; the bracet means multiply so + multiplied by -15

`\mathrm{Subtract\:the\:numbers:}\:-20-15\\=-35`
