Counting numbers

Natural numbers

1

Natural numbers

Counting numbers
1,2,3,4...

2

Whole numbers

Counting numbers plus 0

3

Integers

Whole numbers and their opposites
{...-3,-2,-1,0,1,2,3...}

4

Rational numbers

Can be written as fractions
Includes all whole, natural and integers

5

Irrational numbers

Can't be written as a fraction
Ie. pie symbol

6

Real numbers

Include both rational and irrational numbers - anything goes

7

Coordinate

Location of a point on a number line

8

Plot a point

Place a dot at the location of the point on a number line

10

Absolute value

The distance of the number from 0 on the number line. |-4| is 4

11

If number have different signs...

Ignore the signs and subtract the smaller number from the larger. Attach the sign of the larger number.

12

Subtraction and division are not commutative

True, the order can't be changed

13

Distributive property

Allows us to convert a product into an equivalent sum. 2*(3+4) = 2*3 + 2*4

14

Additive inverse

The sum of a number and its opposite is 0

15

Multiplicative inverse

The product of a number and its reciprocal is 1

16

Order of operations

Pemdas
Parentheses or other grouping symbols
Exponents, square roots, absolute values
Then, left to right
Multiply
Divide
Add
Subtract

17

Grouping symbols

Parentheses, brackets, fraction bar, absolute value, radical symbol

18

Set

Collection of distinct numbers, objects

19

Additive identity

The sum of a number and 0 is the number itself

20

Multiplicative identity

The product of a number and 1 is the number itself
