  2. 4. numbers are those numbers which we use to count such as 1, 2, 3, 4, 5, and so on plus zero.
  3. 5. number is an integer that cannot be grouped in twos. For example, it is not possible to group 5 computers in groups of twos only. Therefore, 5 is an odd number.
  4. 7. triangle A triangle for which all three angles are acute (i.e. between 0° and 90°)
  5. 9. lines are lines in the same plane that do not meet or intersect. The following figure shows four lines that are parallel.
  6. 11. mean of a set of numbers, also called mean, is the sum of the set of numbers divided by the number of numbers in the set.

  3. 6. Symbols [ and ] commonly used to represent the order of operations, along with parentheses and braces (And other less common types.) Informally, all 3 pairs of symbols are referred to as brackets. Brackets are also used to represent matrices amongst other mathematical objects.
  4. 8. A 3-dimensional geometric figure of 6 congruent faces (all squares) where the edges (all 12 of them) have the same length. It is the special case of a cuboid where all lengths are the same. A cube is a 3-dimensional analogue of a square just as a cuboid is a 3-dimensional analogue of a rectangle.
  5. 10. is a set of points that extends in two opposite directions without end
  6. 12. axis is the horizontal number line on the coordinate plane.
  7. 13. are components of an expression. However, we can use the word to define the components of a common fraction, ratio, proportion, or sequence as well.
  8. 15. form of a number, also called word name for a number, is the number written in words.
