Presentation Transcript

  1. It’s all about counting plusses and minuses. Adding integers

  2. Adding integers If you think about adding integers as groups of plusses and minuses it’s not as confusing. - 9 + 6

  3. Adding integers Think of the problem as nine minuses and six plusses - 9 + 6 - - - - - - - - - + + + + + +

  4. Adding integers The minuses and plusses cancel each other out - 9 + 6 - - - - - - - - - + + + + + +

  5. Adding integers So you’re left with three minuses - 9 + 6 - - - - - - + + + + + + - - -

  6. Adding integers The answer is negative three - 9 + 6 - - - - - - + + + + + + - 3 - - -

  7. Adding integers If the numbers are both minuses, just remember that minuses don’t cancel each other out. - 8 - 4

  8. Adding integers This is eight negatives and four more negatives - 8 - 4 - - - - - - - - - - - -

  9. Adding integers All together there are twelve negatives - 8 - 4 - - - - - - - - - - - - - - - - - - - - - - - -

  10. Adding integers The answer is negative twelve - 8 - 4 - - - - - - - - - - - - - - - - - - - - - - - - - 12
