Math Vocabulary Review Part 1

2
Lets take a closer look at each of our math definitions.

3
pattern 1 a planned repetition of something

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

5
function 3 the relationship between two numbers in which one number depends on the other, usually shown in a function table input/output

6
equation 4 a collection of numbers, operation signs, and sometimes variables that names a number, with an = sign

7
algebra 5 a type of math that uses letters or other symbols to represent numbers

8
inequalities 6 statements indicating that two quantities are not equal, utilizing symbols > (greater than) or < (less than) or =

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

10
compute 8 solve, to determine an answer by mathematical procedures

11
distributive property 9 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
associative property 10 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 11 a property of addition and multiplication that states that by changing the order of addends or factors does not change the sum or product = 8 + 5

14
identity property 12 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 13 The property that states: the sum of a number and its opposite is (-9) = 0

16
parentheses 14 ( ) the symbols used to show what operation should be completed first

17
numerical expressions 15 collection of numbers, symbols, and operation signs that stands for a number

18
Expanded 16 a way to write numbers by showing the value of each digit 635 =

19
mixed decimal 17 whole number and a decimal 5.36

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

21
equivalent decimals 19 decimals that name the same number for example:.05=.050=.0500=.05000

22
decimal point 20 this separates the whole number from the decimal number 5.23 and this reads as Five and twenty-three hundredths

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

24
ascending 22 in order from least to greatest number 23, 46, 378, 598, 987

25
exponent 23 how many times the base is a factor 10 4 = 10 x 10 x 10 x 10

26
congruent 24 exactly the same

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

28
Be sure to know these words! You will be tested on them!
