Evaluating Algebraic Equations Define; Variable (p. 71) Algebraic expression (p. 71)

What is an equation? What is a variable? In the Language of Algebra, an equation is the basic number "sentence". An equation is a mathematical expression that contains an equals sign. What is a variable? Symbol the represents one or more numbers. Variables are usually letters Ex: In the algebraic expression, 13 – g, g is the variable

Evaluating Algebraic Expressions When you evaluate an expression; Replace the variable with the given value Solve Ex: Evaluate each expression. Use p=2, n=3, and s=5. 2p + 7 b) p + (n • s)

Writing Algebraic Expressions Read the expression carefully One step at a time, replace the key words in the expression with mathematical operations and keep the numbers & variables. Examples: A temperature of t degrees increased by 5 degrees Five cats fewer than c cats The product of 5 and n nickels A dinner bill of d dollars divided among five friends
