Module 2 Vocabulary Test 7th grade

1.    A __________________________ is any number that can be written in the form  , where p and q are integers.

Rational number        repeating decimal        zero product

Rational number        repeating decimal        zero product

1.    The ________________________ is that of the product of two numbers is zero than at least one of the numbers is zero.

1.    A __________________________is if a certain digit, all remaining digits consist of a block of one or more digits that repeat indefinitely.

Additive inverse       associative        commutative     distributive  

1.    _____________________________simply means changing the sign if the number and adding it to the original number to get an answer equal to 0.    EXAMPLE:       A + -A= 0

Additive inverse       associative        commutative     distributive  

1.    The _______________________property states that when adding or multiplying the grouping symbols can be relocated without affecting the result.

EXAMPLE: a+(b+c) = (a+b)+c              ax(bxc)=(axb) x c

                    2+(5+3) = (2+5)+3             2 x (5x3) = (2X5) x 3

Additive inverse       associative        commutative     distributive  

1.    The _________________________ property applies to addition and multiplication. Meaning the numbers or letters can change/commute to another place and the answer is the same.

EXAMPLE: a+b=b+a                AxB=BxA

                    3+5=5+3               3x5=5x3

Additive inverse       associative        commutative     distributive  

1.    The _______________________ property is applied when you multiply a value by a sum.

EXAMPLE: a(b+c) = ab+ac

Terminating decimal         multiplicative inverse          bar notation

 

   The _______________________ is defined as the reciprocal of a given number.

   ___________________________refers to a horizontal line drawn on repeated numerals.
