INTEGERS

When adding integers with different signs ALWAYS: Subtract and take the sign of the largest number.

Examples:             ( -9)  + (+ 1)  = -8                             (+9)  +  (-1)  =  8

When adding integers with the same signs ALWAYS: Add and take the sign of both numbers.

(+9 ) + (+1)  = +10          ( -9) +  (-1)  = -10
