Using the Introductory Algebra Glossary is simple.

Click thru the slide show and check your knowledge of definitions before you display them.

Slide 3

The numbers used for counting:

{1, 2, 3, 4, .}.

Slide 4

The set of whole numbers is:

{0, 1, 2, 3, 4, 5, .}.

Slide 5

The number above the fraction bar that shows how many equivalent parts are being considered.

Slide 6

The number below the fraction bar in a fraction. It shows the number of equal parts in a whole.

Slide 7

Any number that divides evenly (without remainder) into the given number:

1, 2, 3 and 6 are factors of 6.

Slide 8

The answer to a multiplication problem.

6 is the product of 2 times 3.

Slide 9

A number is factored by writing it as the product of two or more numbers.

6 is factored as 2 times 3.

Slide 10

A natural number (except one) that has only one and itself as factors.

2, 3, 5, 7, 11, 13, and 17 are prime numbers.

Slide 11

A composite number has at least one factor other than itself and one.

Slide 12

The largest common factor of a list of integers or the largest term that is a factor of all terms in the polynomial.

Slide 13

A fraction is in lowest terms when there are no common factors in the numerator and denominator (except 1).
