Some Basics of Algebra I. Translating to an Algebraic Expression To translate problems to equations, we need to know which words correspond to which symbols. ** See Key Words for Solving Word Problems Chart ** Example: (page 10 #10 in Intermediate Algebra by Bittinger)Translate the following into an algebraic expression: Five less than six percent of some number. Let n = the number II. Evaluating an Algebraic Expression Evaluating an algebraic expression simply means that we are substituting a given value for the variable into the expression and then simplifying it as much as possible. ** Review the Order of Operations ! ** Example: (page 10 #22 in Intermediate Algebra by Bittinger)Evaluate for a = 3 and b = 7Example: (page 10 #28 in Intermediate Algebra by Bittinger)Evaluate for a = 7 and b = 5
Example: (page 10 #30 in Intermediate Algebra by Bittinger)Find the area of the triangle given the following base and height: Base = 2.9 m and Height = 2.1 m
