principal square root - ANSWERS-The positive square root of a number.
interval - ANSWERS-A set of numbers between two specified values.
operators - ANSWERS-A word or symbol (such as + or -) that indicates
an operation between values.
commutative - ANSWERS-The 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 - ANSWERS-The symbol which indicates to take the square
root of the number that follows.
additive inverse - ANSWERS-Two numbers equidistant from 0 on a
number line whose sum is 0. For example, 3 and -3.
greatest common factor (GCF) - ANSWERS-The greatest number that is
both a factor of a and a factor of b.
,factor tree - ANSWERS-A graphical method used to identify the prime
factorization of an integer.
integer - ANSWERS-A number, (positive, negative, or zero), that can be
represented without a fractional or a decimal component.
discrete - ANSWERS-A collection of numbers whose values are
distinct, separate, and unconnected.
rational number - ANSWERS-A number that can be written as a ratio of
integers, which means it can be written as a fraction.
product - ANSWERS-The result of multiplying values.
whole number - ANSWERS-A number whose value is 0 or greater and
can be represented without a fractional or a decimal component.
identity property - ANSWERS-The 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 - ANSWERS-The 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 - ANSWERS-The 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 - ANSWERS-In mathematics: a collection of numbers.
order of operations - ANSWERS-A set of rules that defines the order in
which mathematical operations should be performed
multiplicative inverse - ANSWERS-The number you must multiply x by
to get 1. For example, 5 and 1/5.
prime factorization - ANSWERS-Determining the set of prime numbers
whose product is the original integer.
continuous - ANSWERS-A collection of numbers whose values are not
dividable into distinct units.
expressions - ANSWERS-A string of terms that are connected by
division, addition, and subtraction operations.
quotient - ANSWERS-The result of a division expression.
