Algebra Nation Section 1 vocabulary

Associative Property of Addition

Property that states that when adding numbers,
changing the grouping of the numbers or terms
does not change the sum

Associative Property of Multiplication

States that when multiplying numbers, changing the grouping of the numbers or terms does not change the product

binomial

An algebraic expression consisting of two terms

coefficient

A number used to multiply a variable

constant

A fixed value within an equation or expression (a
number or letter that stands for a fixed number)

commutative property of addition

Property that states that the order of the numbers
or terms in a sum can be changed without affecting the sum

commutative property of multiplication

Property that states that the order of the numbers or terms in a product can be changed without affecting the product

degree of a monomial

The sum of the exponents of all the variables of a
monomial

degree of a polynomial

The highest degree of any monomial or term in the
polynomial

distributive property

Property that states that multiplying a single term by
two or more terms inside a set of parentheses yields
an equivalent expression

equation

A statement that the values of two mathematical expressions are equal (indicated by the sign =

equivalent equations

Expressions that are the same, even though they
may look a little different

expression

A mathematical phrase that can contain numbers,
variables, and operators

integers

Any positive or negative number, including zero but
with no fractional or decimal part

irrational number

A real number that cannot be written as a simple
fraction (in the form a/b, where a and b are integers), and when written as a decimal, the decimals do not terminate, nor do they repeat

leading coefficient of a polynomial

The coefficient of the leading term in a polynomial equation

leading term of a polynomial

The term with the highest degree in a polynomial equation

monomial

An algebraic expression consisting of one term

natural numbers

All positive integers greater than zero

negative exponent property

Property of equality that states that a number with a negative exponent should be moved to the other side of the fraction line and the exponent switched to positive

polynomial

An algebraic expression consisting of one term or the sum of several terms that contain different powers of the same variable(s)

power of a power property

States that to find a power of a power, multiply the exponents

power of a product property

States that if there is more than one factor in parenthesis, with an exponent outside the parenthesis, then the exponent is distributed to
every term in the parenthesis

power of a quotient property

States that the power of a quotient is equal to the quotient obtained when the dividend and divisor are each raised to the indicated power separately, before the division is performed

product of powers property

States that the product of two powers with the same base is the base raised to the sum of the
powers (exponents)

quotient of powers property

States that the quotient of two powers with the same base is the base raised to the difference of
the powers (exponents)

radical expressions

any expression containing a radical (? ) symbol, which indicate the root of a number or expression

rational exponent property

Property that states that an expression raised to a rational number can be written as a rational expression

rational exponents

when the exponent is in fraction form

rational number

A real number including those with a fractional or decimal part; it can be written in the form a/b, where a and b are integers

real number

A number that can be any of the following: natural numbers, whole numbers, integers, rational numbers, irrational numbers

standard form of a polynomial

When the monomial terms of a polynomial expression are organized in descending degree
order from left to right

term

A constant, variable, or multiplicative combination
of the two

trinomial

An algebraic expression consisting of three terms

unit

A standard of measurement and exchange used to express a quantity

variable

A letter that represents a quantity that may change within the context of a problem

whole numbers

Positive integers greater than or equal to zero; whole numbers cannot be negative or fractions

zero product property

Property that states that when the product of two or more factors equals zero, one or more of the
factors must also equal zero
