cardinal numbers tell how many (ex. 9 players)
ordinal numbers tell what order (ex. 1st, 13th, ect)
value of a digit depends on the place it occupies
place value
-millions, hundred thousands, ten thousands, thousands, hundreds, tens, ones
can show repeated multiplication as an exponent, exponent shows
how many times the factor appears
positive exponents Rules
-
7^8x7^6=7^(8+
6) 7^^6 =
7^(8-6)
-can use rules to multiply or divide exponents with the same
rules for exponents base 7^8 x 7^6 = 7^(8+6)
7^^6 = 7^(8-6)

, uses powers of 10. the power shows how many zeros
to use ex. 10^0=1
10^1=10
10^2=100
10^(-1)=0.1
10^(-2)=0.01
scientific notation
write whole numbers and decimals in scientific notation. use a
decimal with one number to the left of decimal point
2,345= 2.345x10^3
176.8= 1.768x10^2
0.0034= 3.4x10^(-3)

if next digit is more than 5 round up
rounding
if next digit is less than 5, round down
numbers that can be written as a fraction, can be written as decimals
that terminate or repeat
rational numbers 1=1/1

cannot be
undefined numbers written? 0 in
denominator
1/0?
2 fractions that stand for the same number. multiply or divide the
equivalent fractions
numerator and denominator to dins an equivalent fraction
to change improper fraction to mixed number, divide by denomiator
and look of excess (write excess as fraction)
mixed numbers and improper
fractions to change mixed number to improper fraction multiply denominator
and whole number then add to numerator)
3+2/5 = (3x5)+2 /5= 17/5
integers negative whole numbers, zero, and positive whole numbers are integers
(1) parenthesis
PEMDAS (2)exponents
(3)multiplication and division (4) addition and subtraction
key words (addition) sum, and, more, increased by, how many in all, the total,
less, difference, decreased by, how many left, how much larger, how
key words (subtraction)
many in the rest
key words (multiplication) of, product, times
key words (division) per, quotient, shared, ratio
key words (equals) is, equals
the factors of a number evenly divide the number with no remainder
