⩥ product.
Answer: The result of multiplying values.
⩥ whole number.
Answer: A number whose value is 0 or greater and can be represented
without a fractional or a decimal component.
⩥ identity property.
Answer: 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.
Answer: 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.
Answer: 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.
Answer: In mathematics: a collection of numbers.
⩥ order of operations.
Answer: A set of rules that defines the order in which mathematical
operations should be performed
⩥ multiplicative inverse.
Answer: The number you must multiply x by to get 1. For example, 5
and 1/5.
⩥ principal square root.
Answer: The positive square root of a number.
⩥ interval.
Answer: A set of numbers between two specified values.
⩥ operators.
, Answer: A word or symbol (such as + or -) that indicates an operation
between values.
⩥ commutative.
Answer: 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.
Answer: The symbol which indicates to take the square root of the
number that follows.
⩥ additive inverse.
Answer: Two numbers equidistant from 0 on a number line whose sum
is 0. For example, 3 and -3.
⩥ greatest common factor (GCF).
Answer: The greatest number that is both a factor of a and a factor of b.
⩥ factor tree.
Answer: A graphical method used to identify the prime factorization of
an integer.
⩥ integer.
