##### Across
1. 2. test of factoring is used to factor polynomials of the form Ax� + Bx + C. A, B, and C represent constants and x is the variable.
2. 6. numbers which follow each other in order, without gaps, from smallest to largest.
3. 10. number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.
4. 11. is a number that is bigger than zero. It can be written with a "+" symbol in front of it, or just as a number.
5. 12. To factor a number means to break it up into numbers that can be multiplied together to get the original number.
6. 15. Number can be divided evenly only by 1, or itself. And it must be a whole number greater than 1.
7. 16. expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators
8. 18. says how many times to use that number in a multiplication.
9. 19. fraction is a fraction where the numerator, denominator, or both contain a fraction.
10. 20. is written with a minus sign in front
##### Down
1. 1. is a quantity that may change within the context of a mathematical problem or experiment.
2. 3. two or more non-zero denominators is the smallest whole number that is divisible by each of the denominators.
3. 4. the number below the line in a common fraction; a divisor.
4. 5. the number above the line in a common fraction showing how many of the parts indicated by the denominator are taken, for example, 2 in 2/3.
5. 7. coefficient is defined as a fixed number that is multiplied to a variable.
6. 8. numbers is a real number that cannot be expressed as a ratio of integers, i.e. as a fraction.
7. 9. is a squared (multiplied by itself) number subtracted from another squared number
8. 11. solving may include mathematical or systematic operations and can be a gauge of an individual's critical thinking skills.
9. 13. a numerical quantity that is not a whole number.
10. 14. 2 numbers is the smallest number that they both divide evenly into.
11. 17. is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.
12. 21. is the greatest factor that divides two numbers.
