Chapter1Introduction to Intermediate Algebra

In this chapter, we'll start with discussing numbers and the operations (or actions) we can do with these numbers. Then, we'll introduce the key word of the class: Algebra. Finally, we will close the chapter with Exponents.

You will often hear math teachers say that math is like a language, and they're right! Math has its own rules and regulations much like how English (or other languages) has its own grammar and punctuation rules. The subject of Algebra is meant to organize how we talk about "unknowns".

What this chapter (and book) hopes to develop for you is a basis of how we talk about equations and formulas. Many of the things happening on Earth have some kind of equation or fomula that someone can use. For example, banks use interest formulas or civil engineers still use the Pythagorean Theorem. Of course, a lot of these formulas have been turned into software on your phone or computer. But in order to properly use these devices, one must have a solid foundation in speaking mathematically. Hence, we all learn algebra.
