## Chapter 4, Lesson 4

**4-4.A** add signed numbers

**Evaluate each expression.a.** —42 + 8

**b.**—39 + (—7)

**c.**

**d.**—6 + 2(—3)

**4-4.B** understand the Addition Property of Equality

**For which of the following equations does the solution involve the Addition Property of Equality?**

I) 16 = *m* + 9

II) 11 = 5*p* — 4

III) 3*n* + 3 = 21

**(a)** I and II only **(b)** I and III only

**(c)** I, II, and III **(d)** II only

**4-4.C** solve one-step addition inequalities and graph the solution sets on a number line

**Solve each inequality and graph its solution set.a.** —2 ?

*v*+ 3

**b.**—

*m*+ 2 + 3

*m*< —4 + 2
