This document provides objectives and instructions for translating mathematical phrases to rational algebraic expressions. It begins by reviewing polynomials and defining the symbols, variables, and operations used in algebraic expressions like numbers, parentheses, brackets, braces, and variables to represent values. It then discusses how multiplication, division, addition and subtraction can be represented and notes there are additional terms for these operations. The document provides an activity for students to practice the translations and closes with a reminder of key points to remember and a biblical verse.

7. What is it Translating Mathematical phrases to
Rational Algebraic Expressions
In translating verbal phrases to algebraic
expressions, we need to use numbers, the common
symbols of operations such as +, -, x, ÷, the symbols
for grouping like the parentheses ( ), brackets [ ],
or braces { }, and variables which means any letter
of the English alphabet which is use to represent a
number or several numbers. If a variable stands only
for one specific value, it is called a constant.

8. The operation of multiplication can be represented by
the symbol (×), by ( ) or we can also use dot (.) which is
written halfway up the factors. Division can be
represented by the symbol (÷) or /.
In addition to the words add, subtract, multiply and
divide, there are other terms that also corresponds to
these mathematical operations.
