  1. What happens when we…Add and Subtract Negative numbers?

  2. I would like to introduce you to… A S S and S I D

  3. ASS Add Same Signs + 8 - - 6 = 14 Look at the signs in the middle, if they are the same, then replace them with +

  4. SID Subtract If Different - 8 + - 6 = 2 Look at the signs in the middle, if they are different, then replace them with -

  5. So, who we do we need to help us work out these calculations? or S I D A S S 43 47 + - 4 = 122 - - 4 = 16 - - 4 = 4 + - 4 = 20 0 126

  6. Remember: This is your start number and the new sign in the middle is the direction But what about this one? Can you use all your knowledge of negative numbers so far to find the answer to these calculations? - -6 + -2 = -6 - -8 = -8 2 +

  7. What do you think might happen when we multiply negative numbers? Any ideas? - 4 x - 3 = 4 x - 3 = 12 -12 What about ASS and SID - Can we use them again?

  8. Work through the sheet. Then work in pair to check your answers – do you all agree? If not, why not? Do you think you can work out how we divide negative numbers?
