Whole numbers correct answers The counting numbers beginning with zero: 0,1,2,3,4...
Integers correct answers Positive and negative whole numbers and zero.
Odd numbers correct answers Numbers not divisible by two: 1,3,5,7...
Even numbers correct answers Numbers divisible by two: 2,4,6,8...
Prime numbers correct answers Numbers divisible only by 1 and itself: 2,3,5,7,11,13...
Composite number correct answers Number divisible by more than just 1 and itself:
4,6,8,9,10,12,14,15...
Squares correct answers The result when the numbers are multiplied by themselves: (2x2 = 4),
(3x3 =9): 1,4,9,16,25,36
Cubes correct answers The result when numbers are multiplied by themselves, and again by the
original number, raised to the third power. (2x2x2 = 8), (3x3x3 = 27) ; 1,8,27
Difference correct answers The result of using subtraction.
Product, of, times, at, twice correct answers The result of using multiplication. Example: The
product of 3 and 6 is 18, 3x6 = 18.
, Quotient, divided by, divided into, ratio, half, each correct answers The result of using division.
Sum, total, plus correct answers The result of using addition. Example: The sum of 5,6, and 8,
5+6+8 = 19.
Commutative property of addition correct answers The order does not make any difference. a + b
=b+a
Associative property of addition correct answers The grouping of the numbers does not make
any difference. (a + b) + c = a + (b + c)
Identity element for addition is 0 correct answers Adding any number to 0 gives the original
number. 3 + 0 =3.
Additive inverse property of addition correct answers Is the opposite (negative) of the number.
Any number plus its additive inverse equals 0. 3 + (-3) = 0.
Commutative property of multiplication correct answers Order does not make a difference. a x b
=bxa
Associative property of multiplication correct answers The grouping does not make any
difference. (a x b) x c = a x (b x c)
Identity element for multiplication is 1 correct answers Multiplying any number by 1 gives the
original number. 3 x 1 = 3
Multiplicative inverse is the reciprocal of the number correct answers Any number multiplied by
its reciprocal equals 1.
2 x 1/2 = 1 because both 2's cancel out by cross multiplication.
