Learn: Essential Mathematical Symbols and Operations

Welcome!Today we’re exploring Essential Mathematical Symbols and Operations. This is a key part of iGCSE Mathematics, and understanding these concepts will help you solve many types of problems with confidence.

What Are Mathematical Symbols?Mathematical symbols are used to represent numbers, operations, relationships, and values. They help us express ideas clearly and solve problems efficiently. You see symbols everywhere, such as '+' for addition and '=' for equality.

Arithmetic OperationsArithmetic operations are basic calculations like addition (+), subtraction (−), multiplication (×), and division (÷). These operations are the foundation for solving equations and problems in maths.

What Are Inequality Symbols?Inequality symbols show the relationship between two values when they are not equal. Examples include '' (greater than), '≤' (less than or equal to), and '≥' (greater than or equal to).

What Is Standard Form?Standard form is a way of writing very large or very small numbers using powers of ten. For example, 3000 can be written as 3 × 10³. This makes it easier to work with numbers in scientific and mathematical calculations.

Order of OperationsThe order of operations tells us the correct sequence for solving calculations. Remember the acronym BODMAS: Brackets, Orders (powers and roots), Division and Multiplication (left to right), Addition and Subtraction (left to right).

Using FractionsFractions represent parts of a whole and consist of a numerator (top number) and a denominator (bottom number). For example, ½ represents one part out of two equal parts.

Review Time!Great work! You've learned about key mathematical symbols and operations. Now let’s review what you’ve learned with some final questions.
