Fac, Frac,. Exponents

Rules for Divisibility For 2 the number has to be even. For 3,6,7,9 you add up the sums and if that see if that number is divisible. For 4 the last 2 digits have to be divisible by 4. For 8 the last 3 digits have to be divisible by 8. For 5 the number must end in 5 or 0.
Factor One integer is a factor of another nonzero integer if it divides that integer with a remainder of zero.
Exponents Exponents show repeated multiplication.
Power Powers have bases and exponents. Like 8^6
Base The base of a power is 8 in 8^6
Prime Factorization This is a method of how to find the prime numbers that multiply up to a certain number
Prime Number A prime number for example is 5 because no other numbers can be multiplied into it.
Composite Numbers A composite number is 10 because it has other factors besides 1 and itself.
GCF Greatest Common Factor is when you pick 2 or more numbers for example 10 and 30 you try to find the biggest common factor that goes into both numbers. for 10 and 30 the GCF would be 10.
Equivalent Fractions Equivalent fractions have different numbers but the same value. Like 1/4 and 2/8.
Simplest Form When something is written in simplest form it is written when it cant be reduced any more. 4/8 would reduced into 1/2
Rational Number A rational number is any number you can write as a quotient a/b of two integers where b is not zero. Integers are rational numbers because they can be written as a/1.
Power of a power This is when a exponent is inside parenthesis with another power outside of it. (7^2)^3 This would evaluated as 7^2x3 or 7^6
Order Of Operations P.E.M.D.A.S. parenthesis. powers, multiply, divide, add, subtract
Variable GCF A GCF of two or more numbers that contain a variable.
Find GCF of 78 and 124 2

Rational Numbers (examples) 1, 2, 1.2, 5.5, 0
Negative Rational Number (examples) -1, -2, -5, -1.1
4x^3y^5 times 3x^2yz^2 12x^5y^6z^2
