-5 + (-2) = -5 - 2 = -7

put a mark at -5, five units in the negative direction (to the left of zero)

-2 means subtract 2 from the above mark (from the -5 mark), so move two units in the negative direction (to the left of the -5 mark), and put a new mark
---
the new mark is at -7 on the number line.
