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