"base 10" and base system - Answers -any number times 10,100,1000.... you multiply the first digit by
that number then add those amount of zeros to the end of the number (ie. 375 x100=37500)
-any number divided by 10,100,1000... you divide the first digit by that number then move the decimal
to the left according to the amount of zeroes (ie. 375/1000= .375)
--this is done with any
cardinal numbers - Answers A cardinal number tells "how many." Cardinal numbers are also known as
"counting numbers," because they show quantity. (8 puppies..14 friends)

Ordinal numbers do not show quantity. They only show rank or position. (3rd fastest...6th in line)
Rational number - Answers Any number that can be written as an integer divided by another integer
(fraction)
decimal to fraction and vice versa - Answers -for the amount of numbers in the decimal place that
amount of zeros. (.475= 475/1000)
-move the decimal to the left according to the amount of zeros (234/100= 2.34)
turning a decimal into a percent - Answers move the decimal two places to the right (always use the first
two numbers then the rest of the numbers are after the decimal.
(ie. .2345= 23.45%)
turning a fraction into a percent - Answers cross multiply so......
375/1237 x ?/100
1237?/1237=37500/1237
?=30.32%

(i.e.... 0[squared]= 0........... 1/4 [squared]= 1/8)
expanded notation - Answers The way to write a number that shows the place value of each digit.
Example: The expanded form of 456,759 is 400,000 + 50,000 + 6,000 + 700 + 50 + 9
, scientific notation - Answers using powers of 10 (i.e 10 ^4) to express large numbers (i.e 43,700 is

how to reverse scientific notation - Answers 43.7 x 10^3 = 43700
prime numbers - Answers a number that has only 2 factors, one and itself
composite numbers - Answers A positive integer that has factors other than just 1 and the number itself
factor - Answers any whole numbers that when multiplied together form a product.
