Unit 2 Discussion: 3-2-1 Reflection about Mental Math with Negatives Introduction Negative numbers make algebra complicated! Most mistakes made in solving algebra problems occur because of negative numbers. Although negative numbers are easy to conceptualize (think negative temperature or below sea level), they cause problems when we forget how they behave when adding, subtracting, multiplying, and dividing with negatives. The use of the number line helps us visualize the negative numbers so you are less likely to make these mistakes. Directions Watch a video on using the number line and absolute value technique as a strategy to do mental math with integers: Take notes on the mental math strategies. Post a 3-2-1 reflection about your learning following the directions below. Initial Post (10 points) Your first discussion post must be posted by 11:59 PM (CT) Fridays. Late posts are accepted but will be deducted 1 point each day late. Answer each of the following prompts in complete sentences: 3 things you learned in the video - describe what you found the most helpful. 2 math examples of how to apply your learning - refer to examples in your homework/life where you used the strategies. 1 unresolved question you still have
