- 2. The set of values of the independent variable(s) for which a function or relation is defined.
- 5. Any mathematical process, such as addition, subtraction, multiplication, division, raising to a power, or finding the square root.
- 6. An algebraic equation in which the variable quantity or quantities are raised to the zero or first power.
- 9. A mathematical sentence stating that the two expressions have the same value. Also read the definition of equality.
- 12. A number that is the result of subtraction
- 16. The number of coordinates used to express a position.
- 17. The number that multiplies the variable(s) in an algebraic expression (e.g., 4xy). If no number is specified, the coefficient is 1.
- 18. Any value that does not change.
- 19. A root of a polynomial is a number x such that P(x)=0. A polynomial of degree n has n complex roots.
Down
- 1. A line of infinite extent whose points correspond to the real numbers according to their distance in a positive or negative direction from a point arbitrarily taken as zero.
- 3. A number's distance form zero on a number line. Distance is expressed as a positive value.
- 4. Two lines, two line segments, or two planes are said to be perpendicular when they intersect at a right angle.
- 5. The point of intersection of the x- and y-axes in a rectangular coordinate system, where the x-coordinate and y-coordinate are both zero. On a number line, the origin is the 0 point. In three dimensions, the origin is the point (0, 0, 0).
- 7. A statement or conjecture that can be proven to be true based on postulates, definitions, or other proven theorems. The process of showing a theorem to be correct is called a proof.
- 8. The points where a curve or line drawn on a rectangular coordinate-system graph intersect the vertical and horizontal axes.
- 10. The process of converting a fraction or mixed number, to an equivalent fraction, or mixed number, in which the greatest common factor of the numerator and the denominator of the fraction is one. Simplify also refers to using the rules of arithmetic and algebra to rewrite an expression as simply as possible.
- 11. The result of multiplying numbers together.
- 13. A specific location in space that has no discernable length or width.
- 14. A collection of an infinite number of points in a straight pathway with unlimited length and having no width.
- 15. A number or expression that is multiplied by one or more other numbers or expressions to yield a product.
