COMPREHENSIVE QUESTION REVIEW
◉ 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
◉ A number, (positive, negative, or zero), that can be represented
without a fractional or a decimal component. Answer: integer
◉ A collection of numbers whose values are distinct, separate, and
unconnected. Answer: discrete
◉ Determining the set of prime numbers whose product is the
original integer. Answer: prime factorization
◉ A collection of numbers whose values are not dividable into
distinct units. Answer: continuous
◉ A string of terms that are connected by division, addition, and
subtraction operations. Answer: expressions
