I have two questions for math.

How do I add/subtract an integer

Also, my teacher said 10-20E (Problems in book we have to do)
Is that evens? because the odd answers are in the back of the text book

Thanks,

These sites have great explanations of adding and subtracting integers.

The assignments probably are only for the even numbered problems because of the "E" after the numbers.

Of course, it wouldn't hurt to do all of the problems -- especially since you can check your answers to the odd-numbered problems.

Thanks Ms. Sue you help with everything!!!

You're welcome, Dean.
