When multiple operations are combined in a mathematical expression, which comes first according to BIDMAS?

In mathematical expressions, the order of operations is crucial for obtaining the correct result, and BIDMAS serves as a useful mnemonic to help remember this order. BIDMAS stands for Brackets, Indices, Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

According to this order, operations within brackets must be completed first. This means that any calculations enclosed in brackets are prioritized over all other operations to ensure the structure of the expression is respected. Performing operations in the correct order is fundamental in mathematics, as it influences the outcome significantly. Therefore, identifying that brackets must be addressed first in a mathematical expression is essential for solving problems correctly.

This foundational concept ensures clarity and consistency in calculations, which is why recognizing the importance of brackets as the first operation in BIDMAS is critical for students and practitioners of mathematics.
