Multiplication | The basic idea of multiplication is repeated addition. |
Division | Division is splitting into equal parts or groups. It is the result of "fair sharing". We use the ÷ symbol, or sometimes the / symbol to mean divide |
Factor | Factors are numbers we can multiply together to get another number |
HCF | The highest number that divides exactly into two or more numbers. |
Multiple | The result of multiplying a number by an integer (not by a fraction). |
LCM | The smallest positive number that is a multiple of two or more numbers. |
Power | The power of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. |
Root | Where a function equals zero |
Prime | A Prime Number is a number that has two distinct factors, itself and one. |
Parallel | Always the same distance apart and never touching. |
Calculation | To work out an answer, usually by adding, multiplying etc. |
Percentage | Percent means parts per 100 The symbol is % |
Congruent | The same shape and size. Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other. |
Sequence | A list of numbers or objects in a special order. |
nth term | A formula that describes the pattern in a linear or quadratic sequence. |
Fibonacci | The sequence of numbers: 0,1,1,2,3,5,8,13,21,... Each number equals the sum of the two numbers before it. |
Prism | A solid object with two identical ends and flat sides. The shape of the ends give the prism a name, such as "triangular prism" • The cross section is the same all along its length • The sides are parallelograms (4-sided shape with opposites sides p |
Graph | A diagram of values, usually shown as lines or bars. |
Linear | An equation that makes a straight line when it is graphed. |
Equation | An equation says that two things are equal. It will have an equals sign "=" like this: |
Gradient | How steep a straight line is. Also called "slope". |
Quadratic | An equation where the highest exponent of the variable (usually "x") is a square (2). So it will have something like x2, but not x3 etc. A Quadratic Equation is usually written ax2 + bx + c = 0 |
Power | The power of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. |
Significant Figure | each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit. |
Standard Form | Another name for "Scientific Notation", where a number is written in two parts: • First: just the digits (with the decimal point placed after the first digit), • Followed by: ×10 to a power that will the decimal point back where it should be. |
Diagram | A drawing used to describe something. |
Scatter Graph | A graph of plotted points that show the relationship between two sets of data. |
Algebra | Algebra uses letters (like x or y) or other symbols in place of values, and plays with them using special rules. |
Like Terms | "Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. |
Expanding brackets | Expand is when we remove the ( ) |
Algebraic expression | Numbers, symbols and operators (such as + and ×) grouped together that show the value of something. |
Index Notation | The index of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. |
Ratio | A ratio shows the relative sizes of two or more values. Ratios can be shown in different ways. Using the ":" to separate example values, or as a single number by dividing one value by the total. |
Area | The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle. |
Volume | The amount of 3-dimensional space an object occupies. Capacity. |
Scale | The ratio of the length in a drawing (or model) to the length of the real thing |
Fraction | Part of a whole. |
Integer | A number with no fractional part. |
Multiplication | The basic idea of multiplication is repeated addition. But as well as multiplying by whole numbers, we can also multiply by fractions, decimals and more. |
Division | Division is splitting into equal parts or groups. It is the result of "fair sharing". We use the ÷ symbol, or sometime |
Circumference | The distance around the edge of a circle (or any curvy shape). It is a type of perimeter |
Formula | A special type of equation that shows the relationship between different variables. |
Area | The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle. |
Equation | An equation says that two things are equal. It will have an equals sign "=" like this: |
Variable | A symbol for a number we don't know yet. It is usually a letter like x or y. |
Formulae | A special type of equation that shows the relationship between different variables. |
Frequency | How often something happens (usually during a period of time). |
Polygon | A plane shape (two-dimensional) with straight sides. |
