  1. Choose any 4 of the following to solve.

  4. Each time you choose to skip a question, write 'Skip' in the answer bar.

Some rules to remember when multiplying integers:

+ve times +ve = +ve

+ve times -ve = -ve

-ve times +ve = -ve

-ve times -ve = +ve

When adding or subtracting integers remember the number line. Eg. -5 + 3 is 5 steps backwards and 3 steps forward. Making it a total of 2 steps bakward, ie, -2.
