STATISTICS.
rational number - ansA number that can be written as a ratio of integers, which means it
can be written as a fraction.
product - ansThe result of multiplying values.
whole number - ansA number whose value is 0 or greater and can be represented
without a fractional or a decimal component.
identity property - ansThe property that 0 can be added to any number without changing
the value of the number. Likewise, 1 can be multiplied by any number without changing
the value of that number.
associative property - ansThe property that under certain operations in a multi-step
expression, the computations may be done in any order. Commonly represented as (a +
b) + c = a + (b + c). Addition and multiplication both have this property, but subtraction
and division do not.
perfect square - ansThe product of any integer with itself yields this. So, a number is
this if it can be written as the square of an integer. For example, 9 is this because 3 * 3
= 9. Other examples are 16, 25, 36, 49,...
set - ansIn mathematics: a collection of numbers.
order of operations - ansA set of rules that defines the order in which mathematical
operations should be performed
multiplicative inverse - ansThe number you must multiply x by to get 1. For example, 5
and 1/5.
principal square root - ansThe positive square root of a number.
interval - ansA set of numbers between two specified values.
, operators - ansA word or symbol (such as + or -) that indicates an operation between
values.
commutative - ansThe property that the order of the numbers under the operation does
not change the result. Addition and multiplication have this property: a + b = b + a and
ab = ba.
radical sign - ansThe symbol which indicates to take the square root of the number that
follows.
additive inverse - ansTwo numbers equidistant from 0 on a number line whose sum is 0.
For example, 3 and -3.
greatest common factor (GCF) - ansThe greatest number that is both a factor of a and a
factor of b.
factor tree - ansA graphical method used to identify the prime factorization of an integer.
integer - ansA number, (positive, negative, or zero), that can be represented without a
fractional or a decimal component.
discrete - ansA collection of numbers whose values are distinct, separate, and
unconnected.
prime factorization - ansDetermining the set of prime numbers whose product is the
original integer.
continuous - ansA collection of numbers whose values are not dividable into distinct
units.
expressions - ansA string of terms that are connected by division, addition, and
subtraction operations.
quotient - ansThe result of a division expression.
exponents - ansSometimes called a power, it is a quantity that represents repeated
multiplication.
factor - ansAn integer that divides another integer. We say an integer, x, is a factor of
another integer, y, if the quotient y/x is also equal to an integer.
