Q

Long Division

A

Division, usu. by a number of two or more digits, in which each step of the process is written down.

17
Q

Graphed

A

The Indication of a number with a dot on the number line.

18
Q

Commutative Property

A

The Property that states

Changing the order of two addends/ factors does not change their sum/ multiple

19
Q

Divedend

A

The number that is to be divided in a division problem.

For example,

when you divide

10 by 2

(10 ÷ 2 = 5),

10 is the dividend.

20
Q

Standard Form

Standard form is a way to write numbers using the digits 0-9.

(Another name for scientific notation.)

20
Q

Evaluate

A

To ascertain the numerical value of a function.

21

Q

Addition Property of 0

A

The Property that states

The sum of 0 and any number is that same number.

23
Q

Addition

A

Combining two addends to create a sum.

25

Multiplication sign

A

x

27
Q

Digit

A

A single unit number that uses the symbols 0-9.

29
Q

Rounding

A

Replacing a number with an estimate of that number to a given place value.

30
Q

Subtraction

A

Finding the diffrence between a subtrahend and a minuend.

31
Q

Expression

A

A combination of numbers, symbols, and operations to represent a certain quantity.

For example,

x2 + 2x + 3 is a quadratic expression .

32
Q

A

The distance around a Polygon

35
Q

Subtrahend

A

A number that is to be subtracted from a minuend

8-3=5

3 is Subtrahend

36
Q

A

Scientific notation, (standard form/exponential notation) is a way of writing numbers that accommodates values too… 2x2x2= 23

39
Q

Minuend

A

A number from which the subtrahend is to be subtracted

8-3=5

8 is Minuend

40
Q

Division

A

The operation of finding out how many times the second number will go into the first when dividing one number by a second number.

It is the opposite operation of multiplication,

that is,

a / b = c

is the same as

b × c = a.

41
Q

Associative Property of Addition

A

The Property that states

Changing the grouping of addends does not change their sum.

43
Q
