Algebra 1: Expressions, Equations, and Applications

by Paul A. Foerster

You are about to embark on the course which lays the foundation for virtually all of higher mathematics. In previous courses you have occasionally used a letter to stand for a number you seek to find. Now you will be less concerned about what number the letter represents, and will concentrate on things that are true just because it is a number. The letters used will be called variables, because they can stand for different numbers at different times. Expressions containing these variables can represent quantities in the real world, such as how high a ball is above the ground at various times after it was thrown. By learning how to operate with such expressions, you will be able to predict such things as how to operate with such expressions, you will be able to predict how high the ball is at a given time, how long it takes to reach a given height, and when it will be back down.

I'm not sure how to show a different edition, but mine is the 2006 Classics Edition by Prentice Hall. I didn't read chapter 14, and I didn't do the exercises. I was trying to stay ahead of my 8th grader in algebra. I understood a lot of it, but because I didn't practice, I am sure I couldn't do the word problems. The explanations were solid, detailed, and helpful, using math terminology; and I've not seen word problems like that. The math was applied to real life through the use of word problems that require quite a bit of reasoning skills and analysis. It was definitely tougher than Math U See. But I'm glad we went through MUS first, because the first half of Foerster's then was review with shoring up technical terms, learning how to apply the math through word problems, and the addition of a few things not covered in MUS, such as the quadratic formula. I felt that MUS had done an excellent job at explaining the algebra, and it was helpful to go through MUS first. However, once we hit the end of the book, there were more and more things we hadn't seen, or at least, not seen in depth as it was in Foerster's. I am so glad I didn't have to lead my child through Foerster's, though, because then I would have had to put in a lot more time for practice and understanding. Please take a look at Karena Flynn, an excellent online tutor using this excellent algebra text. https://www.libertytutorials.com/
