Subtracting Integers

Watch this video about subtracting integers.

When figuring out +9 – (-9) =

Use the analogy of a pot of warm water that is at (+9) degrees. If you remove NINE NEGATIVE DEGREES (-9), the water is actually getting 9 degrees WARMER. That is why +9 – (-9) = 18 instead of 0. Remember, TWO NEGATIVES EQUAL A POSITIVE! +9 – (-9) = CHANGES to +9 +9 = +18. Watch the video for extra clarification.

Integers Video (Watch for Monday)

Introduction to negative numbers:

Please watch these videos on integers as a refresher and/or introduction as we prepare to work with them in the coming weeks. If you have questions, you can post them on Edmodo, ask someone you trust over the weekend or ask me on Monday/Tuesday in class.

Happy viewing!
