Lesson 1-2 Comparisons

Comparisons - A problem that involves someone or something that has "more" or "less" of something than someone or something else. Real world example = height, weight, and number of items just to name a few. Compare is the base word. Attached is a video of our class discussing comparisons.

Lesson 1-6 Equations and Parentheses
1. Understand everyday applications of multiplication and division
2. Generate and solve algebraic equations that involve grouping with parentheses.

This lesson is the beginning of the order of operations. We also have a pnuemonic device that makes the order of operations easy to remember. We call the order of operations PEMDAS. Here is the order of what needs to be done first in algebraic equations.

Remember to start from left to right. Also division and multiplication are interchangable in the order of operation, and addition and subtraction are also interchangable.

Here is a video to help you see pemdas in action:
