2. Multiplying and Dividing Real Numbers

3.  Multiplying two numbers with the same sign is always positive. ◦ (pos) x (pos) = (pos) ◦ (neg) x (neg) = (pos)  Multiplying two numbers with different signs is always negative. ◦ (pos) x (neg) = (neg) ◦ (neg) x (pos) = (neg)

4. 1.) 6·(-2) = 2.) (-4) · (-5) = 3.) -3 · 6 = 4.) 2·(-5)·(-4) =

5. If the exponent is even, then the answer is always positive. If the exponent is odd, then the answer is the same sign as the original. Examples: 1.) 5 4 =2.) (-5) 4 =3.) (-4) 3 = 4.) 4 3 =5.) (-6) 2 ·(3) 3 =
