MULTIPLICATION return**

**In algebra we concern ourselves with
multiplying signed numbers such as - 4 and +
3. **

**So lets multiply
them - 4(+ 3) = - 12 What does the answer tell
us about multiplying **

**a**** negative number by a positive number? Answer **

**Of course since multiplication is
commutative 3(- 4) also = - 12**

**As in arithmetic a positive number
multiplied by a positive number**

**equals**** a positive number ex + 5(+6) = + 30 By
tradition we do not **

**write**** the positive sign. So the previous problem would look
like 5(6) = 30**

**What happens if we multiply two negative
numbers together?**

**For example -4(-6)
= answer**

**Would the answer to the following problem
be positive or negative?**

**3(-4)(5)(-2) = answer **
