Terms 3

By Cameron H

CellIn geometry, a cell is a three-dimensional element that is part of a higher-dimensional object.

Column

This is a column of numbers:

Examples:

1225179214

Variable

A letter or other symbol that represents a number. A variable can represent one specific number or it can stand for many different numbers.

D=2 C=45

E=3 B=5

Algebraic expression

An expression that contains a variable.

B+C=A

B=2 C=4

D=6R=5E=1

D=E+R

Row

Arrangement of objects or data in a horizontal line or side by side is called a Row

Evaluate (a formula)

To find a value for. To evaluate a mathematical expression, replace the variable (if there are any) with numbers, then carry out the operations.

A+B=C1+2=3

D-R=M5-4=1

Formula

A general rule for finding the value of something. A formula is often written using letters, called variables that stand for the quantities involved.

A=3 B=4 A+B=?

D-F=?

D=12F=4

General pattern

A list of numbers that follow a certain sequence or pattern.

Rate

A comparison by division of two quantities with unlike units.

Special case

A special case is the defining formula of a function.

A-B=C5-3=2

R*R=E6*6=36

Square root

The square root of a number n is a number that, when multiplied by itself, gives the number n.

* =

5*5=25

Unit rate

A rate with 1 in the numerator.
