| Additive inverses | Two numbers whose sum is 0 are additive inverses of one another. Example: 3/4 and -3/4 are additive inverses of one another because 3/4 + (-3/4) = (-3/4) + 3/4 = 0. |
| Complex fraction | a fraction a/b where A and/or B are fractions. (nonzero) |
| Congruent | Two plane or solid figures are congruent if one can be obtained from the other by a rigid motion (a sequence of rotations, reflections, and translations.) |
| Computation algorithm | A set of predefined steps applicable to a class of problems that gives the correct result in every case when the steps are carried out correctly. See also: computation strategy |
| Computation Strategy | purposeful manipulations that may be chosen for specific problems, may not have a fixed order, and may be aimed at converting one problem into another. |
| Counting On | A strategy for finding the number of objects in a group without having to count every member of the group. Example: If a stack of books are known to have 8 books and 3 more books are added to the top, it is not necessary to count the stack all over again. |
| Dilation | A transformation that moves each point along the ray through the point emanating from a fixed center, and multiplies distance from the center by a common scale factor. |
