- 6. when at least one of them is not zero, is the largest positive integer that divides the numbers without a remainde
- 7. A decimal number that continues infinitely, or without end.
- 9. is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero.
- 10. The addition method of solving systems of equations is also called
- 12. that contains two or more variables
- 14. of two numbers is the smallest number (not zero) that is a multiple of both.
- 15. Two lines on a plane that never meet. They are always the same distance apart.
- 16. equation between two fractions or rational expressions, one can ..........to simplify the equation or determine the value of a variable.
- 20. is a natural number greater than 1 that has no positive divisors other than 1 and itself
- 21. A decimal number that has digits that do not go on forever.
Down
- 1. Two or more lines that meet at a point
- 2. they share no common factors. In other words, there is no number, other than 1, that divides both a and b.
- 3. is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself
- 4. The zero and the counting numbers (1,2,3,...) make up the set of whole numbers
- 5. Real numbers that have infinite, but non-repeating, decimal representation
- 8. is any real number that cannot be expressed as a ratio of integers.
- 11. is a positive integer that has at least one positive divisor other than one or the number itself.
- 13. is a procedure or formula for solving a problem.
- 17. Lines that have one and only one point in common
- 18. is a proven proposition which is used as a stepping stone to a larger result rather than as a statement of interest by itself.
- 19. Two lines that lie on top of one another
