What is Algebra?

Arithmetic deals with operations on

numbers while algebra uses variables, or letters, to create mathematical

models to represent the world around us. These mathematical models are

expressed as algebraic equations that can be solved to find an unknown

value, or can be studied to identify trends and make predictions.

Mathematical Words for Algebra

• Sum: A sum of two or more numbers is the answer to an addition

  problem.

• Difference: A difference between two numbers is the answer to a

  subtraction problem.

• Quotient: A quotient is the answer to a division problem.

• Product: A product is the answer to a multiplication problem.

• The quantity of: The quantity of indicates that there are two or more

  terms combined to make one term.

• The sum of and the difference of: These two terms are like the

  quantity of and are illustrated with parentheses.

• From: Subtract eight from 10 is written as 10 – 8 and not 8 – 10.

• Less than: Two less than 20 is written as 20 – 2 and not 2 – 20

• Triple: Triple the amount of last year’s 4,000 attendees is written as

  3 × 4,000

Defining Parts of an Algebraic Expression

It is important that you know the meanings

of these words since they will be used to explain more involved procedures

with algebraic equations.

Constant: A fixed number that remains the same and does not

change.

Variable: A letter or symbol that represents a number in an algebraic

expression.

Coefficient: The number or symbol multiplied by a variable in an

algebraic expression.

Term: A number, variable, or a coefficient multiplied by one or more

variables.

Factor: Numbers that are multiplied together in an algebraic expression

Algebraic expression: A mathematical sequence containing one or

more variables or numbers connected by addition or subtraction.
