Across
- 2. fraction is a common fraction that has a numerator that is bigger than (or equal to ) the denominator.
- 4. numbers are those numbers which we use to count such as 1, 2, 3, 4, 5, and so on plus zero.
- 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.
- 7. triangle A triangle for which all three angles are acute (i.e. between 0° and 90°)
- 9. lines are lines in the same plane that do not meet or intersect. The following figure shows four lines that are parallel.
- 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.
- 14. A series of events that are regularly repeated in the same order.
- 16. is a unit of length in the metric system of measurement that is equal to 1000 meters.
- 17. is a comparison of two numbers or quantities by division
- 19. number is any number less than zero. The following numbers are negative numbers
- 20. Originally a positive integer that divides another given positive integer a whole number of times.

- 1. is a polygon with six sides. Here are some examples of hexagons.
- 3. is a branch of mathematics that focuses on the study of points, lines, angles, surfaces, and solids.
- 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.
- 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.
- 10. is a set of points that extends in two opposite directions without end
- 12. axis is the horizontal number line on the coordinate plane.
- 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.
- 15. form of a number, also called word name for a number, is the number written in words.
- 18. A binary mathematical operation that represents the abstract concept of the formation of a larger collection
