The distance a number is from zero on the number line. For example, 5 is 5 units away from zero. It would be written as 5

absolute value


An angle whose measure is less than 90 degrees

acute angle


The operation, or process, of calculating the sum of two numbers or quantities

addition


Two angles that share a ray, thereby being directly next to each other

adjacent angles


Affine ciphers use linear functions to scramble the letters of secret messages

affine cipher


Stepbystep procedure by which an operation can be carried out

algorithm


Angles located outside a set of parallel lines and on opposite sides of the transversal

alternate exterior angles


Angles located inside a set of parallel lines and on opposite sides of the transversal

alternate interior angles


A ray that divides an angle into two congruent angles

angle bisector


The number of square units needed to cover a surface

area


This property applies both to multiplication and addition and states that you can group several numbers that are being added or multiplied (not both) in any way and yield the same value. In mathematical terms, for all real numbers a, b, and c, (a+b)+c=a+(b+c) or (ab)c=a(bc)

associative property


It is better to avoid this sometimes vague term. It usually refers to the (arithmetic) mean, but it can also signify the median, the mode, the geometric mean, and weighted means, among other things

average


An estimate of the amount that will be gained in a game of chance, calculated by multiplying the probability of winning by the number of points won each time

average expected payoff


There are three axioms of probability: 1. Probability is always more than zero 2. The chance that something happens is 1,or 100% 3. If two events cannot both occur at the same time, the chance that either one occurs is the sum of the chances that each occurs
