VARIABLES, FORMULAS, AND ALGEBRAIC EXPRESSIONS
Variables are mathematical representations of quantities. First, we'll look expressions with variables.
Formulas use variables to make mathematical statements. Formulas give mathematical instructions to solve problems. We will examine the interest formula closely.
To write algebraic expressions, a common agreement amongst mathematicians is to use certain keywords to signal mathematical operations. Some keywords and phrases often used are sum, difference, product, quotient, more, less, increased by, and decreased by. We'll examine which operations match which expressions.
