This study guide provides information to help prepare for a math test. It lists order of operations as a topic, explaining that mathematical problems must be solved following the PEMDAS method: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. Two example problems are worked through step-by-step to demonstrate applying the order of operations, with the first problem solved as 40 - 2 x 16 = 8 and the second as 5 x 3 + (7 - 1) = 21.
