When subtracting integers:
Change the subtraction sign to addition
Change the sign of ONLY the next number
to its opposite.
Follow the rules for addition
EXAMPLE
14 – (-12)
14 – (-12) Change the operation to addition
14 – (-12) Change the next number to its opposite
Then follow the rules for addition. The signs
are now the same, so add and give the common
sign. 14 + 12 = 26.
