Across
- 3. sequence: A sequence of numbers in which each number can be computed by adding the same amount to the previous number.
- 5. grid A grid used to illustrate values of algebraic expressions.
- 6. Clue
- 8. law of multiplication For any three numbers a, b, and c, it is always true that (a(b))(c)=a(b(c)).
- 9. A constant that a variable or expression is multiplied by
- 11. A number that is raised to a power.
- 13. law of addition For any three numbers a, b, and c, it is always true that (a+b)+c=a+(b+c).
- 14. function ceiling(x) is the closest integer which is greater than or equal to x.
Down
- 1. like terms Using the distributive law to add any two multiples of an expression such as x. For example, you can simplify 4x+5x into 9x.
- 2. even Have a profit of zero (that is, make exactly as much money as you spend).
- 4. fit line 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.
- 5. value The distance a number is from 0
- 7. plot A box with “whiskers” showing the median, quartiles, and extremes (least and greatest values) of a collection of data values.
- 8. The study of mathematical symbols and the rules for manipulating those symbols
- 10. denominators Multiplying both sides of an equation by some nonzero number that turns all the fractions in the equation into integers
- 12. of symmetry A line that you can flip (or reflect) a graph across that results in the same graph.
