Rules for Divisibility 2. If it ends in an even number 3. Add them all up 4.Are the last two digits in your number divisible by 4? 5. Ends in 0 or 5 6. Goes into 3 and 2 8.if the last 3 digits are divisible by 8 9. Add all the digits in the number 10. End in 0
Factors Factors are what goes into the numbers.
Order of Operations PEMDAS
Exponent 3^2= 3x3= 9
Base The base is the whole number
Power The power is the number above the base
(-3)² means (-3)x(-3)= 9
-3² means 3x3= -9
Prime Numbers A prime number is a whole number that only has two factors which are itself and one.
Composite Numbers All even numbers are composite including 0
GCF Greatest Common Factor
Variable GCF x^2y^5, xy^3
Prime Factorization 120
Finding Prime Factorization using GCF 78 and 124 do a factor tree
Simplifying Variable expressions 12x^2y^5/8x^4y^2
Rational Numbers A number that can be simply put into a fraction
Negative Rational Numbers 4x^3y^5 * 3x^2yz^2
Power of Power Rule (x^3y^5)^4
Zero exponent Rule x^0
Negative exponent Rule x^-3
Write without negative exponents x^-3y^2/a^2b^-3
Rewrite without a fraction bar x^3y^2/a^2b^3
Rewrite without zero or nagative exponents and simplify x^-2y^2z^0/x^-2y^-3
