This program on problem solving is the 3rd of 13 episodes designed to help students prepare for the mathematics section of the GED exam. Problem solving is an acquired skill that can be improved through practice. People need to know how to get the answer more than having the answer itself. A host and several guests present 5 principles for math problem solving in the context of a person wanting to buy a car. The first step is to identify and understand the problem. One should focus on the problem to ensure one knows how to proceed. Second, one should locate all needed information. This includes doing any homework beforehand and reading the fine print. The easiest decision isn't necessarily the smartest one. Third, one sets up the problem, looking for similarities to a previous problem that could guide one's approach, as well as cues that reveal the functions to be performed. Fourth, one works the calculations, seeking a ballpark estimate before reaching the final answer. When calculating, it's essential to know the PEMDAS order of operations: a) first solve within parentheses; b) simplify exponents; c) multiply and divide from left to right of equation; d) add and subtract from left to right. Lastly, it's important to check that one's answers make sense.
