Question

(01.01 MC)Why is 3 + (−5) equal to −2?

Answer 1

Step-by-step explanation: Since the 5 is a negative you would subtract 3 instead of add. I help to use an number line.. start at -5 on the number line then move 3 spaces forward and yo get 2.

Answer 2

we usually see a bare + or - in front of a grouping symbol, like +( and such, well, it really means to have a 1 and a times sign as well, namely +1*, so +( really means +1*(

`\bf 3+(-5)\implies 3+1* (-5)\implies 3-5\implies ~~\begin{matrix} 3-3 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~-2`
