Across
- 1. An arrangement of items in a specific order; order matters.
- 7. The measure of how likely an event is to happen, ranging from 0 to 1.
- 9. A U-shaped curve formed by a quadratic function, like y = x².
- 10. A rectangular arrangement of numbers in rows and columns, used in solving equations and transformations.
- 11. Numbers greater than zero.
- 13. Formed when two rays meet at a common endpoint called the vertex; measured in degrees or radians.
- 16. The longest side of a right triangle, opposite the right angle.
- 17. The middle value when numbers are arranged in order.
- 19. A branch of mathematics dealing with change and motion, including derivatives and integrals.
- 21. A list of numbers arranged in a specific pattern or order (example: 2, 4, 6, 8…).
- 23. A line that touches a curve or circle at exactly one point; also a trigonometric ratio (opposite ÷ adjacent).
- 24. A letter or symbol that stands for an unknown or changeable number (example: x, y).
- 25. A relationship where each input (x) has exactly one output.
- 27. Measures how a function’s output changes with respect to its input; shows the rate of change.
- 28. A comparison between two numbers showing how many times one value contains another (example: 2:3).
- 29. The number that appears most frequently in a data set.
- 30. In a right triangle, it is the ratio of the length of the opposite side to the hypotenuse.
Down
- 2. Numbers less than zero.
- 3. A number that tells how many times to multiply the base by itself (example: in 2³ = 8, 3 is the exponent).
- 4. The average of a set of numbers (sum of all values ÷ number of values).
- 5. A selection of items where order does not matter.
- 6. In a right triangle, it is the ratio of the length of the adjacent side to the hypotenuse.
- 8. A part of an expression separated by plus or minus signs (example: in 3x + 2y – 5, each part is a term).
- 11. A constant approximately equal to 3.1416; the ratio of a circle’s circumference to its diameter.
- 12. The difference between the highest and lowest values in a data set.
- 13. The process of finding the total or sum by combining two or more numbers.
- 14. A mathematical statement showing that two expressions are equal (example: 2x + 3 = 7).
- 15. The number placed before a variable (example: in 5x, 5 is the coefficient).
- 18. A single number calculated from a square matrix that helps solve equations or find inverses.
- 20. The branch of math that uses symbols and letters to represent numbers and relationships.
- 22. Means “nothing” or “zero”; in math, it can refer to a null set (no elements) or null matrix (all zeros).
- 26. A number that means nothing or no quantity; the point between positive and negative numbers.
- 27. A line that passes through the center of a circle and touches both sides of its boundary.
- 30. A part of a circle bounded by two radii and the arc between them (like a “slice” of pie).
