1) The document contains notes from a math lesson on January 14, 2014. It includes assignments that are due, an upcoming test, and warm-up exercises on angles and simplifying expressions. 2) The warm-up questions ask students to name alternate interior angles from a figure, determine the measure of an angle if another is given, simplify exponential expressions, and graph a linear equation. 3) The lesson notes explain the rules for multiplying and dividing expressions with the same base: when multiplying, add the exponents, and when dividing, subtract the exponents.

Lesson 57:
FYI...Remember:
--multiplying & the "bases" are the same - add the exponents
--dividing & the "bases" are the same - subtract the exponents
