| Question | Answer |
| Natural Numbers | Numbers that occur naturally Eg. (not 0)(whole numbers) 1, 2, 3 ... |
| Whole Numbers | Numbers that represent a WHOLE (no decimals) |
| Integers | Whole, natural numbers that are both positive and include the negative counterparts (no decimals) |
| Rational Numbers | All numbers that can be written as a FRACTION. Includes all natural, whole numbers and integers Eg. 6/1, 2/1, 0, -3/1 ... |
| Irrational Numbers | All numbers that cannot be written as a FRACTION. Eg. pi |
| Repeating Decimal | A decimal that has a repeating sequence of numbers. It is rational! Eg. 2.353535... |
| Irrational Decimal | A decimal that has a random, infinite sequence of digits. Eg. pi 3.14159... |
| Equivalent Fractions | Fractions that look different but are equal Eg. 2/3 = 4/6 |
| Alike Fractions | Fractions that have the same denominator Eg. 4/6 and 5/6 |
| Factor | Numbers to be multiplied together |
| Product | Answer to a multiplication problem |
| Quotient | Answer to a division problem |
| Inverse/ Reciprocal | Opposites or same operations going different directions Eg. + and - |
| Perfect Square | A number that divides into itself. It has two identical factors. Eg. 9 = (3x3) |
| Square Root | To find the root of a perfect square. Eg. The square root of 9 is 3 |
| Prime Number | A number whose factors are only one and itself Eg. 1, 2, 3, 5, 7, 11, 13, 17, 19, 23... |
| Prime Factors | The smallest multiples a number can break down into(all prime numbers) Eg. 100 = 2x2 x 5x5 |
| Exponent | The number of times a base is multiplied by itself to be a power Eg. 3^2 = 2 is the EXPONENT |
| Base | The number that is multiplied by itself an X number of times depending on the exponent Eg. 3^2 = 3 is the BASE |
| Power | Repeated multiplication is done to the base determined by the exponent |
| Expanded Form (of a power) | Is the form of the entire equation Eg. 3^2 is 3 x 3 |
| Exponential Form (of a power) | Is the form of the power Eg. 3 x 3 = 3^2 |
| Standard Form (of a power) | The solution to the power Eg. 3^2 = 9 |
| x^1 | A number to the power of 1 equals itself |
| x^0 | Any number to the power of 0 equals 1 |
| BEDMAS or PEMDAS | Acronym for Brackets(Parenthesis), Exponents, Division/Multiplication, Addition /Subtraction |
| Distributive Property | Exponents applying to brackets are applied equally to every term(number) in the brackets |
| Volume | Formula: l x w x h Is the total space an object takes up x^3 |
| Surface Area | Formula: side area x Sa x Sa x Sa.... Is the areas of all the sides added together x^2 |
| Volume of a Cube | lwh or l^3 (all sides are equal, remember?) |
| Surface Area of a Cube | 6 x side area (all sides are the same) |
| Volume of Triangular Prism | l x h/2 (triangle) x w |
| Surface Area of Triangular Prism | 2(l x h/2) (triangle) + base + 2 (other rectangles) |
| Volume of Rectangular Prism | l x w x h |
| Surface Area of Rectangular Prism | 2(side area x) + 2(side area y) + 2(side area z) |
| Volume of Cylinder | pi x radius^2 x height |
| Surface Area of Cylinder | (2 x pi x radius x height) + (2 x pi x radius^2) |
| Volume of Rectangular Pyramid | l x w x h /3 |
| Surface Area of Rectangular Pyramid | Area of base + 4(slant x base /2) |
| Volume of Cone | pi x radius^2 x height/3 |
| Surface Area of Cone | pi x radius^2 + pi x radius x slant height |
| Volume of Sphere | 4/3 x pi x radius^3 |
| Surface Area of Sphere | 4 x pi x radius^2 |
| Constant | Has a constant, known value |
| Variable | Has a value that can change |
| Co-efficient | A constant that is multiplied by a variable |
| Reciprocal | To flip or do the opposite Eg. + is the opposite of - |
