Factors, Fractions, Exponents

Rules For Divisibility 2: even number 3: sum of digits = 0 4: last 2 digits are divisible by 4 5: ends in 5 or 0 6: if it is divisible by 2 and 3 8: last 3 digits are divisible by 8 9: sum is divisible by 9 10: ends in 0
Factors numbers that are multiplied to get a number
Order of Operations PEMDAS (parenthesis, exponents, multiply/divide, add/subtract
Exponent small number by a bigger number that shows how many times to multiply the number by itself
Base the bigger number next to the exponent
Power how many times you multiply the base by itself (example: second power= b*b
Prime Numbers numbers that have no more than 2 factors
Composite Numbers numbers that have more than 2 fators
GCF greatest common factor: the biggest factor between a group of numbers (example: 2 and 4 GCF=2
-3 squared means -3*3
(-3) squared means (-3)(-3)
rational numbers examples: 1/2, 2, -1/16
prime factorization 120 2^3*3*5
prime factorization using GCF 78 and 124 2
12x^2y^5/8x^4y^2 3y^3/2x^2
negative rational numbers write with - sign on the top (example -2/1
4x^3y^5*3x^2yz^2 12x^5y^6z^2 rule for multiplying exponents: add the exponents that have the common variable
(x^3y^5)^4 x^12y^20 rule for the power of a power: multiply the exponent by the exponent outside of the parenthesis
x^0 1 rule for zero power: always = 1
write without negatives x^-3y^2/a^2b^-3 y^2b^3/a^2x^3
without fraction bar x^3y^2/a^2b^3 x^3y^2a^-2b^-3
without zero or negative exponents and simplify x^-3y^2z^0/x^-2y^-3 y^5/x
