This week, we are going to wrap-up everything that we have learned in Pre-Algebra. Recall that we learned how to:
- define these terms: variable; algebraic expression; signs of operation; order of operations. Lesson review here.
- translate a word sentence into a mathematical expression. Lesson review here.
- write algebraic expressions. Lesson review here.
- apply the order of operations to solve math equations. Lesson review here.
- turn word sentences into algebraic expressions. Lesson review here.
- balance equations to solve for variables (solve for 'x'). Lesson review here.
Here's a video from Discovery Education that would help you understand these concepts:
