The document discusses rules for adding integers with the same or different signs. When adding integers with the same sign, add the numbers and keep the sign. When adding integers with different signs, subtract the absolute values and keep the sign of the integer with the greater absolute value. It provides examples of applying these rules to expressions involving integers.

1. Frayer Model Examples Nonexamples Definition Characteristics absolute value a number's distance from zero on the number line

3. Adding Integers Same Signs Add and Keep The sum of two positive integers is positive and the sum of two negative integers is negative. Different Signs Subtract Find the difference of the absolute value of two integers with different signs. Keep the sign of of the integer with the greater absolute value.

4. Try some: 1. 2 + (-6) 2. -4 + 9 3. -22 + (-16) 4. 60 + (-13)

8. Evaluate each expression for n = -12 1. n - 25 2. 36 + n 3. n + 18 + n
