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