Unit 3: Whole Numbers and Integers

Question 1

quotient

Answer 1

The result of dividing.

Question 2

multiplication

Answer 2

In mathematics, this operation is the act of adding the same number multiple times. This operation is often denoted by the dot sign.

Question 3

real number

Answer 3

Any number on the number line. Real numbers include whole numbers, integers, rational numbers, and irrational numbers.

Question 4

subtraction

Answer 4

Taking one or more values away from another.

Question 5

divisor

Answer 5

In a division problem, it is the number dividing

Question 6

front-end estimation

Answer 6

Only rounding the numbers in the place furthest to the left (greatest place value).

Question 7

operator

Answer 7

A word or symbol that indicates an operation between values

Question 8

distributive property

Answer 8

A mathematical principle used to multiply one term by multiple terms. This principle is employed when there are parentheses around multiple terms, which are in turn multiplied by a single term.

Question 9

expressions

Answer 9

A finite group of numbers or symbols that are connected by operators and have mathematical validity.

Question 10

odd number

Answer 10

All integers that are not even; any integers not divisible by 2.

Question 11

addition

Answer 11

Finding the total of two or more values.

Question 12

difference

Answer 12

The result of one number being subtracted from another number

Question 13

exponent

Answer 13

Sometimes called a power, it is a number that shows how many times the base is multiplied by itself.

Question 14

number line

Answer 14

A line in which points are matched to real numbers. The numbers increase in value as you move to the right

Question 15

remainder

Answer 15

The amount that is left over after division

Question 16

associative property

Answer 16

A property that holds if 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 satisfy this property

Question 17

order of operations

Answer 17

A set of rules that defines the order in which mathematical operations should be performed.

Question 18

dividend

Answer 18

In a division problem, the number being divided into.

Question 19

rectangular array

Answer 19

An arrangement of columns and rows that shows a product in the form of a rectangle.

Question 20

sum

Answer 20

The result of two or more numbers being added together. The result of addition.

Question 21

negative number

Answer 21

A number whose value is less than zero. On the number line, these numbers are to the left of zero.

Question 22

rounding

Answer 22

A method of estimating in order to make working with a number easier.

Question 23

division

Answer 23

Splitting values into equal parts or groups.

Question 24

even number

Answer 24

All integers that are divisible by 2

Question 25

commutative property

Answer 25

The property that the order of the numbers under the operation does not change the result. Addition and multiplication satisfy this property: a + b = b + a and ab = ba.

Question 26

multi-step expression

Answer 26

An expression with more than two values and two or more operators that requires multiple steps to be solved.

Question 27

absolute value

Answer 27

The value of a number in terms of its distance from zero on the number line.

Question 28

product

Answer 28

The result of multiplying.

Question 29

parentheses

Answer 29

In mathematics, these are used to separate operations within an expression and to indicate which operations should be performed first. They are also used to denote multiplication when a number or variable lies directly outside them.

Question 30

operation

Answer 30

A mathematical calculation or process. The most common are addition, subtraction, multiplication, and division.
