Objective:

To check solutions of equations and translate verbal phrases into algebraic expressions.

Vocabulary

Notes:

Notation - Inequality Symbols

Notice that each has the word "is".

When translating between verbal phrases and algebraic expressions write the numbers, variables, and symbols in the order that you come across them when the problem reads "is less than", "is greater than", and "is more than".

Note: If the problem reads "less than", "greater than", or "more than" (without the word "is") then reverse the order of the variable and the number and use addition or subtraction.  Do NOT use the inequality symbols.

Example:  Four is less than a number translates to 4 < n, while four less than a number translates to n − 4.
