Algebra Unit 2 - Part 1

The branch of mathematics that uses alphabetic symbols

algebra

This expression is an expression that contains variables or a combination of constants and variables with one or more operators

algebraic

the number written together with a variable to indicate the product of the number and the variable in a term

coefficient

when you multiply terms in an expression, you must remember to multiply both the

coefficient and the variables

A term relating to abstract ideas

conceptual

A value that does not change

constant

The source or origin of a word is called its

derivation

to find the numerical value of an expression by substituting a number for each variable and simplifying the expression means to

evaluate an expression

a variable raised to the power of 1

first degree variable

symbols that are used to indicate a group of terms that should be treated as one term or to indicate operations that must be performed before other operations are attempted in an expression

grouping symbols

Terms that contain the same set of variables raised to the same power

like terms

You can combine terms by adding or subtracting only in the terms are

like terms

This expression is a combination of terms with one or more operators grouped together to represent a numerical value

mathematical

This expression is an expression that contains only numbers with one or more operators

numerical

A symbol that indicates a mathematical operation (+,-,x,/)

operator

a set of rules used to determine the proper order for performing operations in an expression that involves more than one operation

order of operations

a symbol that shows the relationship between two expressions, that they are either equal, indicated with an equal sign, or unequal, indicated with an inequality sign

relation symbol

a variable raised to the power of 2

second degree variable

to perform all the indicated operations means to

simplify an expression

part of a mathematical expression consisting of a constant, or a variable, or the product of a number and a variable, separated from other terms by an operation or a relation symbol

term

A value, usually in the form of a letter or symbol, that can change or that represents an unknown quantity

variable
