Algebra I
Today we discussedWe moved on to begin a discussion about coordinate graphing, ordered pairs, and relations. We discussed what a relation is and how domain and range are defined. We also discussed what the inverse of a relation is, and how to represent relations in four different ways: ordered pairs, table, mapping and coordinate graphing.

Pre-Algebra
Today we discussedToday we moved into solving two-step equations. These equations have two operations going on. We discussed solving using inverse operations, and using the reverse order of operations to figure out where to start solving. Also, keep in mind that when you have a fraction that has an operation in the numerator, there is an understood set of parentheses there. That operation will need to be "undone" last.
