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.
