1) The document contains notes from a math lesson on October 9th 2012. It includes assignments due, warm up questions, formulas for area of rectangles and squares, examples of exponent problems to solve, and more example problems labeled A through O. 2) The lesson covers exponents, including the meaning of base, exponent, and square root. Formulas are given for calculating the area of rectangles using length x width and the area of squares using side x side. 3) Examples involve solving exponent problems like 4 cubed, 1/2 squared, and 10 to the sixth power. Letter examples A through O are unlabeled exponent calculations.

Lesson 20 Warm­Up:
1) Use words to write 18700000.
2) The perimeter of a certain square is 2 feet.
How many inches long is each side of the square?
3) Arrange these numbers in order from least to greatest:
1/3, ­2, 1, ­1/2, 0
4) Simplify: 3/4 ­ (1/4 + 2/4)
5) What is the probability of rolling an even number with one roll of a
number cube?
