Algebra Stuff

2. The distance a number is from 0.
4. A number that is raised to a power.
5. A constant that a variable or expression is multiplied by.
9. In an arithmetic sequence, the amount that can be added to each number to get the next one.
10. Have a profit of zero (that is, make exactly as much money as you spend).
12. Multiplying both sides of an equation by some nonzero number that turns all the fractions in the equation into integers.
13. ceiling(x) is the closest integer which is greater than or equal to x.
14. A grid used to illustrate values of algebraic expressions.
15. A line that you can flip (or reflect) a graph across that results in the same graph.

1. For any three numbers a, b, and c, it is always true that (a+b)+c=a+(b+c).
3. When the points on a grid are not all on a straight line, but seem to have a somewhat linear pattern, you can find a line that is the “best fit” (closest) to the points.
6. A box with “whiskers” showing the median, quartiles, and extremes (least and greatest values) of a collection of data values.
7. The study of mathematical symbols and the rules for manipulating those symbols.
8. Using the distributive law to add any two multiples of an expression such as x. For example, you can simplify 4x+5x into 9x.
11. A sequence of numbers in which each number can be computed by adding the same amount to the previous number.
