Welcome!Today we'll explore essential mathematical symbols and operations, a key topic in iGCSE Mathematics. These symbols and operations are used to solve problems and understand mathematical relationships. Let's get started!
What are Mathematical Symbols?Mathematical symbols are special characters used to represent operations, relationships, and values in maths. They make it easier to express mathematical ideas clearly and concisely.
Basic Arithmetic OperationsThe key arithmetic operations are addition (+), subtraction (−), multiplication (×), and division (÷). These operations help us calculate and manipulate numbers in various mathematical problems.
Quick check: Which symbol is used for multiplication?

Order of OperationsIn mathematics, the order of operations tells us the sequence to follow when performing calculations. The acronym BODMAS helps us remember this: Brackets, Orders, Division/Multiplication, Addition/Subtraction.
Equality and Inequality SymbolsEquality is represented by =, meaning two values are equal. Inequality symbols include (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to). These symbols help us compare values.
Which of the following are inequality symbols? (Select all that apply)

Fractions and DecimalsFractions represent parts of a whole, such as 1/2 or 3/4. Decimals are another way to express parts of a whole, such as 0.5 or 0.75. You can convert between fractions and decimals by dividing.
A fraction has a {{blank0}} and a {{blank1}}.

Prime Numbers and FactorsA prime number is a number greater than 1 that has exactly two factors: 1 and itself. A factor is a number that divides another number exactly, leaving no remainder.
Quick check: Which of the following is a prime number?

PercentagesA percentage is a way of expressing a number as a fraction of 100. For example, 25% means 25 out of 100. Percentages are often used in financial calculations like discounts and interest rates.
