In this second lecture, I discuss operations with fractions and percentages. A nice review of fractions and percentages before getting into algebra.
I hope you find these resources. If you have any questions, put them in the comments below.
At the beginning of this year, I'll be publishing a series of lectures on algebra, starting with the basics and completing with quadratic functions. This week: whole numbers, integers, and decimals. Part of this lecture includes sign rules and order of operations.
One way to divide fractions is to find an LCD and divide across. See the "Short" for a long example. It would've been easier to keep it - change it - flip it.
In this video, I discuss the basics of how to use the TI-30XS multiview calculator. Topics include order of operations, exponents, fractions, verifying expressions and equations, and how to use the table feature.
