- 2. a branch of mathematics that uses symbols or letters to represent variables, values or numbers. They can then be used to express operations and relationships and to solve equations
- 4. Number a number with at least one other factor besides itself and one. Hint: NOT a prime number.
- 5. A way of writing rational numbers (numbers that are not whole numbers), also used to represent ratios or division. Hint: Has a numerator and denominator
- 6. The steepness or incline of a line, determined by reference to two points on the line. The equation of this is y=mx+b
- 10. Numbers The set of positive integers. This is only regular whole counting numbers that sometimes includes zero.
- 11. The unit used to measure the size of an angle. Outside of math, it is used as a measurement of temperature.
- 14. The opperation of summing. In other words, this is the what you do when you are using addition.
- 15. The correspondence in size, form or arrangement of parts on a plane or line. Hint: Mirroring is used to describe this word.
- 18. Equation An algebraic equation in which each term is either a constant or the product of a constant. The first power of a single variable, and whose graph is therefore a straight line.
- 19. The part of mathematics concerned with the size, shape and relative position of figures. It also studies lines, angles, shapes and their properties
- 20. two geometrical figures are congruent to one another if they have the same size and shape. So one can be transformed into the other by a combination of translation, rotation and reflection
Down
- 1. Numbers whole numbers, both positive (natural numbers) and negatives. This includes zero but excludes all decimals or fractions.
- 3. A number showing how many times the base is used as a factor. Also known as, the little numbers above or below numbers or variables.
- 4. a branch of mathematics involving derivatives and integrals.Used to study motion and changing values.
- 7. An algebraic expression or equation with more than one term. They are constructed from variables and constants using only the operations of addition, subtraction, multiplication and non-negative whole-number exponents.
- 8. The measure of the number of cubic units needed to fill a space. You calculate this when working with three dimensional figures.
- 9. The measure of the amount of surface on a flat surface. Another word for region.
- 12. A mathematical statement that two quantities are equal. This usually involves variables and numbers on both sides.
- 13. Plane a plane with two scaled perpendicular lines that intersect at the origin. It has an X and Y axis.
- 16. The difference between the highest and lowest number in a set of data. Outside of math,it is defined as a set of different things.
- 17. value distance between a number and zero. To show this, you put bar lines on either side of the number.
