State the rule for multiplying and dividing integers…. If the signs are the same, If the signs are different, the answer will be positive. the answer will be negative.

1. -8 * 3 What ’ s The Rule? Different Signs Negative Answer * -61 Same Signs Positive Answer (-3)(6)(1) Just take Two at a time (-18)(1) ÷ (-3) (20/-5) - (-4) Start inside ( ) first

7. At midnight the temperature is 8°C. If the temperature rises 4°C per hour, what is the temperature at 6 am? How long Is it from Midnight to 6 am? How much does the temperature rise each hour? 6 hours +4 degrees (6 hours)(4 degrees per hour) = 24 degrees 8° + 24° = 32°C Add this to the original temp.

8. A deep-sea diver must move up or down in the water in short steps in order to avoid getting a physical condition called the bends. Suppose a diver moves up to the surface in five steps of 11 feet. Represent her total movements as a product of integers, and find the product. W h a t d o e s T h i s m e a n ? Multiply (5 steps) (11 feet) (55 feet) 5 * 11 = 55
