Directions: Using the integers -3 to 3, at most one time each, fill in the blanks to make each equation true.

### Hint

### Hint

What do you know about adding and subtracting integers?

### Answer

### Answer

There are many possibilities. 2 + -3 = -1 and 1 – 3 = -2; 1 + 2 = 3 and -3 – (-1) = -2

The second solution is incorrect. -3 – 1 = -4

It should read -3 – (-1) = -2

Thanks for pointing this out Kara. I have edited the solution.

zero is part of the integer set. Should the directions also state that zero can’t be used?

I let them use zero. Solutions like -2 + 1 = -1 and 0 – (-3) = 3 were found. Made for some good discussion about the meaning of 0.
