Question

Determine the answer to (−3) + (−5) and explain the steps using a number line.

Answer 1

Ok well let's examine:

+ (- 5)

We have a positive negative number, which is just the same as a normal negative. Adding a negative is the same as subtracting it's positive:

-3 + 5

Answer 2

Adding a positive to a negative is the same when flipped over:

-3 + 5
5 - 3

So we have a simpler expression to work with.

Answer 3
