Lesson 1-5 Adding Integers

The sum of an integer and its opposite is 0 Opposites are also called additive inverses 5 + (-5) = x + (-x) =

Rules for adding integers SAME SIGN Add the two numbers and bring the sign along 15 + 55 -22 + (-7) -18 + (-6)

Rules for adding integers DIFFERENT SIGNS Subtract the smaller number from the bigger number….then use the sign of the bigger number. -12 + 5 23 + (-34) -16 + 27

Find the sum -12 + (-6) + 15 + (-2) 1 + (-3) + 2 + (-10)

Write a numerical expression and then find the sum You borrow $20, and then pay back $18 You deposit $120, and then write a check for $25
