Two negative signs together change the sign to a positive sign.

Using the distributive property with the 7 you would have -(-7), the two negatives would make it +7

So you end up with -8 + 7

Strike441 [17]

Answer:

We know

1 jar = 500 buttons

5 people bring 330 buttons EACH

We can find/solve by...

people x buttons = total buttons

total buttons / 500 = number of jars needed

5 x 330 = 1650

1650 / 500 = 3.3

Your answer:

4 jars

Explanation

It's impossible to have 3.3 jars, so you must round up.
