Multiplying and Dividing Positive and Negative Numbers
1 When multiplying or dividing two integers you need to check the signs. Firstly multiply and divide the numbers as normal. Use these rules to find the sign for the answer:
1.1 Two like signs (both + or -) give a positive result. Two unlike signs (one + and the other -) give a negative result.
2 Examples:
2.1 -5 x 3 = -15
2.2 -10 x -2 =20
2.3 -12 divided by -2=6
2.4 15 divided by -3 = -5
