This animated video demonstrates multiplication of positive and negative numbers using faces ( a smile and a frown) as visual clues. ( The video does not include audio.) ( :58)

In this video, a teacher demonstrates adding integers with different signs. He explains the process of subtracting the absolute value of the numbers and then attaching the sign of the number with the largest absolute value to the answer. The proble...ms are worked on a white board as they are explained. (01:01)[more]

This video is a step-by-step lesson about addition and subtraction of multiple integer numbers. The video explains working left to right. The narrator uses humor and it is an easy video to follow. (08:47)

This video song is for the pre-algebra and algebra crowd on how to subtract negative integers. The explanations with the visuals are very good. This is a great resource to introduce and/or review integers in the middle school classroom. (1:50)

This video explains how to add both positive and negative numbers on a number line. It shows how this skill transitions into pre-algebra by making the addition problem a simple equation (e.g. 5+x=9). (07:05)
