Factors numbers used to multiply to get a number
Order of Operations work inside grouping symbols then simplify any terms with exponents, then multiply and divide in order from left to right, then add and subtract in order from left to right
Exponent An is the number that shows how many times a basic is used as a factor
Base the original number
Power is any expression in the form of a^ power can also be referred to exponent
Prime Numbers is an integer greater than 1 with two positive factors 1 and itself
Composite Numbers is an integer greater than 1 with more than two positive factors
GCF the greatest common factor of two or more numbers is the greatest factor that the numbers have in common
Variable GCF the greatest common factor that includes variables
Prime Factorization the prime factorization of a number is the expression of the number as the product of its prime factors
Finding Prime Factorization using GCF you take that number times 1
Rational Numbers any number you can write as a quotient of two integers were the bottom number is not 0 or 2
Multiplying Exponent Rule when you multiply them you add what is the exponent of the same base
Zero Exponent Rule when you have a zero exponent it is its self but in a equation it becomes nothing
Negative Exponent Rule you move it to the top of the bar and then it becomes positive
(-3)^2 9
12x^2y^5 8x^4y^2 3x^2y^3 2
write the without negative exponents x^-3y^2 a^2b^-3 y^2b^3 x^3a^2
rewrite with out fraction bar x^3y^2 a^2b^3 x^3y^2A^-2b^-3
rewrite without zero or negative exponents and simplify x^-3y^2z^0 x^-2y^-3 y^5 x^1
