ADDING INTEGERS

• When adding different signs, find the difference of both numbers and take the sign of the number you have more of.

(-12) + 27 = 

I have an addition sign (that's good).  My numbers have two different signs, so I have to find the difference of 12 and 27.  It is 15.  Now, I have more positives (27) than negatives (-12).  So, my answer is positive.  Answer is 15.
