Math Vocabulary Review Part 1

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

1 pattern a planned repetition of something

2 product The answer in multiplication 8 x 9 = 72

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

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

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

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 =

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

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

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)

(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)

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

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

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

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

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

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 =

17 mixed decimal whole number and a decimal 5.36

18 mixed number whole number and a fraction 5 3 4

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

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

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

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

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

24 congruent exactly the same

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

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