Same signs give a positive: \(3 + (+2) = 3 + 2 = 5\) Same signs give a positive: \(3 - (-2) = 3 + 2 = 5\) Different signs give a negative: \(3 + (-2) = 3 - 2 = 1 ...

Negative numbers get lower the further we move left, so -5 is less than -2. To add and subtract numbers always begin counting from zero. When adding positive numbers, count to the right.
