Q

Ellipsis

A

Three dots(…) mean that the list is infinite or goes on without and

1
Q

Counting numbers

Or natural numbers

A

The numbers we say when we count

{1,2,3,4,5,…}

2
Q

{ }

A

These symbols are called braces. One use of braces is to designate a set.

3
Q

Whole numbers

A

Including zero with the set of counting numbers forms the set of whole numbers.
{0,1,2,3,4…}
The set of whole numbers does not include any numbers less than zero, between zero and one, or between any consecutive counting numbers.

4
Q

The four fundamental operations of arithmetic

A

Addition, subtraction, multiplication, and division

5
Q

Addends

A

The numbers in an addition problem that are added together

6
Q

Sum

A

The answer to an addition problem

7
Q

Subtrahend

A

The number in a subtraction problem being subtracted

8
Q

Minuend

A

The number in a subtraction problem being subtracted from.

Minuend-subtrahend=difference

9
Q

Difference

A

The result of a subtraction problem

10
Q

Product

A

The result of a multiplication problem

11
Q

Factor

A

1) The numbers in a multiplication problem that are being multiplied together
2) a whole number that divides another whole number without a remainder.
3) to write as a product of factors. We can factors the number 6 by writing it as 2 x 3.

12
Q

Ways to indicate multiplication

A

4 x 5
4 · 5
4(5)
ab

13
Q

Dividend

A

The number being divided

14
Q

Divisor

A

The number being used to divide

15
Q

Quotient

A

The result of a division problem

16
Q

Ways to indicate division

A
Division sign ( ÷ )
Division box (        )
Division bar ( - )
17
Q

Variable

A

Letters used to represent numbers in formulas and expressions

18
Q

Evaluate

A

We evaluate an expression by calculating its value when the variables are assigned specific numbers

19
Q

Fact family

A

A group of three numbers related by addition and subtraction for by multiplication and division. Four mathematical fact statements can be formed using the numbers in a fact family.

The numbers 3, 4, and 7 are a fact family they make these four facts:
3+4=7, 4+3 = 7, 7-3 = 4, 7-4 = 3

20
Q

Identity property of addition

A

States that when zero is added to a given number, the sum is equal to the given number.
a +0 = a

21
Q

Commutative property of addition and multiplication

A

a+b=b+a, a x b=b x a

Changing the order of addends or factors does not change the sum.

22
Q

Identity property of multiplication

A

States that when a given number is multiplied by 1 the result equals the given number.

a x 1 = a

23
Q

Inverse operations

A

Operations that “undo” one another. Addition and subtraction or multiplication and division.

24
Q

The property of zero for multiplication

A

States that when he number is multiplied by zero the product is zero

25
Q

Perfect square

A

When we multiply a counting number by itself the product is a perfect square

26
Q

associative property of addition or multiplication

A

States that the grouping of addends or factors does not change the sum or product.
(A + B) + C = A + (B + C)
(A x B) x C = A x (B x C)

27
Q

Number line

A

A line for representing and graphing numbers each point on the line corresponds to a number

28
Q

Equation

A

A statement that uses the symbol “=” to show that two quantities are equal

29
Q

Origin

A

The zero point on a number line

30
Q

Positive numbers

A

Numbers to the right of the origin. Greater than zero

31
Q

Negative numbers

A

Numbers to the left of the origin. Less than zero

32
Q

Integers

A

Include all of the counting numbers as well as their opposites (their negatives) and the number zero

33
Q

Comparison symbol

A
Greater than (>)
Less than (<)
Equal to (=)
34
Q

Factors of a number

The whole numbers that divide the number without the remainder

35
Q
