Why is 3 + (−5) equal to −2? 1- Because it is 5 units to the left of 0 on a horizontal number line 2- Because it is 5 units to the right of 3 on a horizontal number line 3- Because it is 5 units to the left of 3 on a horizontal number line 4- Because it is 5 units to the right of 0 on a horizontal number line

Vocaloid:

3 + (-5) when you add a negative number, you are subtracting so you can re-write this as 3 - 5 based on that, what do you think? when we subtract, do we go left or right on the number line?

LaylaSanaii:

I think it's B

LaylaSanaii:

I meant C

Sebav14:

Yeah me too

Vocaloid:

C (or choice 3) is correct. when you subtract, you go left on a number line. so yes, you start at 3 and go left 5 units. well done.
