algebra 1 terms

3. A constant that a variable or expression is multiplied by.
5. law of addition: For any three numbers a, b, and c, it is always true that (a+b)+c=a+(b+c).
8. 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.
9. value: The distance a number is from 0.
11. denominators: Multiplying both sides of an equation by some nonzero number that turns all the fractions in the equation into integers.
13. The study of mathematical symbols and the rules for manipulating those symbols.

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. sequence: A sequence of numbers in which each number can be computed by adding the same amount to the previous number.
4. plot: A box with “whiskers” showing the median, quartiles, and extremes (least and greatest values) of a collection of data values.
6. law of multiplication: For any three numbers a, b, and c, it is always true that (a(b))(c)=a(b(c)).
7. function: ceiling(x) is the closest integer which is greater than or equal to x.
8. even: Have a profit of zero (that is, make exactly as much money as you spend).
10. A number that is raised to a power.
12. grid: A grid used to illustrate values of algebraic expressions.
14. of symmetry: A line that you can flip (or reflect) a graph across that results in the same graph.
