2
Let’s take a closer look at each of our math definitions.

3
1 pattern a planned repetition of something

4
2 product The answer in multiplication 8 x 9 = 72

5
**function the relationship between two numbers in which one**

3 function the relationship between two numbers in which one number depends on the other, usually shown in a function table input/output

6
**a collection of numbers, operation signs, and sometimes variables that **

4 equation a collection of numbers, operation signs, and sometimes variables that names a number, with an = sign

7
**letters or other symbols**

5 algebra a type of math that uses letters or other symbols to represent numbers

8
**inequalities statements indicating that two quantities are not equal,**

6 inequalities statements indicating that two quantities are not equal, utilizing symbols > (greater than) or < (less than) or =

9
7 variable a symbol used to represent a number A + 6 = 9

10
**answer by mathematical procedures**

8 compute solve, to determine an answer by mathematical procedures

11
**distributive property**

9 distributive property The property that states that multiplying a sum by a number gives the same result as multiplying by each number then adding the products 3(5+6) = (3x5) + (3x6)

12
**(4 x 6) x9 = 4 x (6 x 9) associative property**

10 associative property in addition and multiplication, changing the order of the grouping does not change the sum or product (4 x 6) x9 = 4 x (6 x 9)

13
**commutative property 5 + 8 = 8 + 5 a property of addition and**

11 commutative property a property of addition and multiplication that states that by changing the order of addends or factors does not change the sum or product 5 + 8 = 8 + 5

14
**identity property the property that states that by adding 0 or by**

12 identity property the property that states that by adding 0 or by multiplying by 1 does not change a number a + 0 = a a x 1 = a

15
**inverse property The property that states: the sum of a number and**

13 inverse property The property that states: the sum of a number and its opposite is 0 9 + (-9) = 0

16
**parentheses ( ) the symbols used to**

14 parentheses ( ) the symbols used to show what operation should be completed first

17
**numerical expressions**

15 numerical expressions collection of numbers, symbols, and operation signs that stands for a number

18
**Expanded a way to write numbers by showing the value of each digit**

16 Expanded a way to write numbers by showing the value of each digit 635 =

19

20
18 mixed number whole number and a fraction 5 3 4

21
**equivalent decimals decimals that name the same number for example:**

19 equivalent decimals decimals that name the same number for example: .05=.050=.0500=.05000

22
**decimal point this separates the whole number from the decimal number**

20 decimal point this separates the whole number from the decimal number 5.23 and this reads as Five and twenty-three hundredths

23
21 descending in order from greatest to least number 435, 367, 129, 67

24
**ascending in order from least to greatest number 23, 46, 378, 598, 987**

22 ascending in order from least to greatest number 23, 46, 378, 598, 987

25
**exponent how many times the base is a factor = 10 10 x 10 x 10 x 10 4**

23 exponent how many times the base is a factor 4 = 10 10 x 10 x 10 x 10

26
24 congruent exactly the same

27
25 factor the numbers that are multiplied to give a product 6 x 8 = 48
