Step 3. Keep the product positive.

() 3 () 40 = 120

c. ())()(

Step 1. Determine which multiplication rule applies.

()− )()(

The signs are opposites (one negative and one positive), so use

Rule 6.

Step 2. Multiply the absolute values, 3 and 40.

() 3 () 40 = 120

Step 3. Make the product negative.

()− )()( =− 120

d. ())()(

Step 1. Determine which multiplication rule applies.

() 3 () 40

The signs are opposites (one positive and one negative), so use

Rule 6.

Step 2. Multiply the absolute values, 3 and 40.

() 3 () 40 = 120

Step 3. Make the product negative.

()^3 ()^40 =−^120

e. ()()

Step 1. Determine which multiplication rule applies.

() 358 () 0

0 is one of the factors, so use Rule 7.

Step 2. Find the product.

()^358 ()^00
