Rules of Positive and Negative Signs Multiplication - Division -Addition - Subtraction Free Worksheet

 

This video from MooMoo Math and Science explains the rules for working with positive and negative numbers in multiplication, division, addition, and subtraction.

For multiplication and division, the same rules apply:

If the signs are the same, the answer is positive.

If the signs are different, the answer is negative.

For addition:

If the signs are the same, add the numbers and keep the sign.

If the signs are different, subtract the numbers and keep the sign of the number with the larger absolute value.

For subtraction:

Subtract and keep the sign of the larger number.

If subtracting a negative number, change it to addition (subtracting a negative becomes adding a positive).
