ToggleThe absolute value of a number is the distance between that number and zero on a number line. It is always non-negative. For example, the absolute value of both -5 and 5 is 5, denoted as ∣5∣=5 and ∣−5∣=5.
Add Maths (short for Additional Mathematics) is an advanced-level mathematics subject offered in many secondary school curricula, covering topics like algebra, calculus, and trigonometry beyond the standard math curriculum.
An addition sentence is a mathematical statement that shows two or more numbers being added together, along with the sum. For example, 3+4=7 is an addition sentence.
The additive inverse of a number is the value that, when added to the original number, equals zero. For example, the additive inverse of 5 is -5 because 5+(−5)=0.
Advanced functions refer to more complex mathematical functions, typically studied in higher-level math courses. These may include polynomial, exponential, logarithmic, and trigonometric functions.
Algebra is a branch of mathematics that uses symbols (often letters like x or y) to represent unknown values in equations and expressions. It involves operations like addition, subtraction, multiplication, and division to solve for these unknowns.
In geometry, an altitude is the perpendicular segment from a vertex of a triangle to the line containing the opposite side. It represents the height of the triangle.
The amplitude is the maximum distance a wave (such as a sine or cosine function) reaches from its equilibrium or center position. In trigonometry, amplitude describes the height of the wave.
In geometry, the apex refers to the highest point or vertex of a cone or pyramid.
An endpoint is a point at one end of a line segment or the starting point of a ray. A line segment has two endpoints, while a ray has one endpoint and extends infinitely in one direction.
An equation is a mathematical statement that shows the equality between two expressions. For example, 2x+3=7 is an equation where 2x+3 and 7 are equal.
A math expression is a combination of numbers, variables, and operations (like +, -, ×, and ÷) that represents a value. For example, 3x+2 is an expression.
The identity element is a number that, when combined with another number using a particular operation, leaves the other number unchanged. For example, 0 is the identity element for addition because x+0=x, and 1 is the identity element for multiplication because x×1=x.
An identity is an equation that is true for all possible values of the variables involved. For example, x+0=x is an identity in addition.
In GCSE Maths, an identity refers to an equation that holds true for all values of the variable(s). It is often represented with the symbol ≡, indicating that the two sides are identically equal for any input.
The independent variable is the variable that you control or choose in an experiment or equation. In the function y=2x+3, x is the independent variable, as it affects the value of y.
An operation in math is a process like addition, subtraction, multiplication, or division applied to numbers or variables to produce a result.
In mathematics, an argument refers to the input of a function. For example, in the function f(x)=x2, x is the argument.
Arithmetic is the branch of mathematics that deals with basic operations such as addition, subtraction, multiplication, and division.
ASA (Angle-Side-Angle) is a rule in geometry that states if two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the triangles are congruent.
This refers to a strategy in solving math problems where you first ask yourself what information is provided (the given) and what needs to be found. It helps in organizing the approach to solving the problem.
In math, at least means a value is greater than or equal to a certain number. For example, saying “at least 5” means the value is 5 or more.
An axiom is a fundamental statement or proposition that is accepted as true without proof. Axioms serve as the starting point for further reasoning and arguments.
The base in math refers to the number that is being raised to an exponent. In the expression 23, 2 is the base, and the expression means 2×2×2.
Base ten blocks are a visual aid used to teach place value, addition, subtraction, and other basic math concepts. They represent units (1), rods (10), flats (100), and cubes (1,000).
In educational systems like CBSE, basic maths refers to the general-level mathematics curriculum, while standard maths covers more advanced concepts and is designed for students aiming for higher studies in math-intensive fields.
In the CBSE curriculum, basic maths is a simpler version of the math exam for students who don’t wish to pursue mathematics in higher studies, while standard maths includes more advanced topics for students who may continue studying math at higher levels.
BIDMAS stands for Brackets, Indices, Division and Multiplication, Addition and Subtraction. It’s the order of operations used to solve mathematical expressions.
A distribution is bimodal if it has two distinct modes, or peaks, in its frequency of data points. This means the data has two different values that occur most frequently.
The BODMAS rule is used to remember the order of operations when solving math problems. It stands for Brackets, Orders (i.e., powers and square roots, etc.), Division, Multiplication, Addition, and Subtraction. The order matters in how you perform calculations.
