To add integers you simply move from one number the required
number steps in a positive direction.
Example
2 + 3 means you start at the number 2 and move 3 in the
positive direction
So our answer would be 5
This process is the same if we have a negative value as well.
Example
-3 + 6 means you start at -3 and count 6 steps in the
positive direction
So your answer will be 3
To subtract integers you simply need to remember that
subtracting an integer is the same as adding its opposite.
Example
5 6 = 5 + (-6) = -1
9 4 = 9 + (- 4) = 5
Or
-6 (-3) = -6 + (3) = -3
-8 (-4) = -8 + (4) = 4 |
