🛎️ What is a Mathematical Expression?
- A mathematical expression is a calculation made using numbers and operations (+, −, ×, ÷).
- For example, 3 + 4 × 2 is an expression, but 3 + 4 = 7 is an equation.
🛎️ What is BIDMAS?
- BIDMAS tells you the correct order to calculate.
- It stands for Brackets, Indices, Division, Multiplication, Addition, Subtraction.
🛎️ Applying BIDMAS
- If there are brackets, calculate what is inside them first.
- If two operations are at the same level, work from left to right.
🛎️ Dealing with Multiple Brackets
- If there is more than one set of brackets, start with the innermost brackets.
- Then continue working outwards, following BIDMAS.
