| Question | Answer |
|---|---|
| Rules for Divisibility | 2-Ends in even number, 3- Sum of digits Divisible by 3, 4- Last two digits divisible by 4, 5- Ends in 0 or 5, 6- If divisible by 2 and 3, 8- Last 3 digits divisible by 8, 9- Sum of digits divisible by 9, 10- Ends in 0 |
| 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 |
