Thurs Sept 23

Homework:

• finish "Quiz show" worksheet
• finish -10x3 worksheet

Rules for multiplying integers:

1. positive x positive = positive
2. negative x positive = negative
3. positive x negative = negative
4. negative x negative = positive

These are the same rules we've been using for double signs. 
A quick trick:  if the signs are the same, the answer is positive; if the signs are different, the answer is negative.
