Rules for Divisibility | 2- ends with even # 3- sum of digits ÷ 3 4- last 2 #'s ÷4 5- ends in 5 or 0 6- if ÷ by 2 & 3 8- last 3 #'s ÷ 8 9- sum of digits ÷ 9 10- ends with 0 |
Factors | Numbers that divide evenly into another number |
Order of Operations | PEMDAS |
Exponent | Writing repeated multiplication times you multi. the number by itself |
Base | →2² |
(-3)² means | Positive |
-3² | Negative |
Prime Numbers | Any number that has 2 factors (1 & itself) |
Composite Numbers | Any number that has 3 or more factors |
GCF | Greatest Common Factor largest number divisible by 2 or more numbers |
Variable GCF (x²y⁵xy³) | xy³ |
Prime Factorization | Use prime trees |
Finding Prime Factorization using GCF (78 124) | Make prime tree, then find like terms and simplify. |
Simplifying Variable Expressions 12x²y⁵/8x⁴y² | 20x⁶y⁷ |
Rational Numbers | Any number that can be written in the form a/b where b does not equal 0 |
Negative Rational Numbers | Write with the negative sign either out side the fraction or with the numerator. |
Multiplying Exponent Rule | Multiply powers with the same base |
Power of Power Rule | Multiply the exponents |
Zero Exponent Rule | Any number written to the zero power the answer is always 1 |
Negative Exponent Rule | Rewrite with reciprocal with positive power. |
Write with negative exponents | 5^-3 (3)^-2 |
Rewrite without a fraction bar | Write in all one line, then combine like terms. x³y²/a²b³= x³y²a²b³ |
Rewrite without zero or negative exponents and simplify | x^-3y²z⁰/x^-2y^-3=x²y³y²/x³= xy |
