In the realm of mathematics, the proper order of operations is like the foundation of a building โ it provides the necessary structure for complex calculations to be carried out accurately. Two acronyms that often come to the forefront when discussing these mathematical structures are the BODMAS rule and the BIDMAS rule. These acronyms serve as guidelines for determining the sequence in which different mathematical operations are performed within a given expression.

BODMAS is a mnemonic that stands for **Brackets**, **Orders**, **Division**/Multiplication, and **Addition**/**Subtraction**. It is a widely recognized rule that dictates the sequence in which mathematical operations should be performed to achieve accurate results.

**Brackets**: The first step involves solving expressions enclosed within brackets. This can include parentheses (), square brackets [], or curly braces {}. The operations within the innermost set of brackets should be performed first.**Orders**: Orders refer to operations involving powers and roots. Any exponentiation or square root calculations should be done following the bracket evaluations.**Division**/**Multiplication**: After tackling the brackets and orders, the next step is to perform any division or multiplication operations from left to right in the given expression.**Addition**/**Subtraction**: The final step involves addition and subtraction, again carried out from left to right. These operations should be performed after addressing brackets, orders, and division/multiplication.

The BODMAS rule ensures that expressions are solved systematically, preventing ambiguity and generating consistent results. Let's consider an example to illustrate the application of what is BODMAS in maths:

**Brackets**: Inside the parentheses, 12 รท 4 equals 3. So, the expression becomes 5 + 8 * 3 - 32.**Orders**: The square of 3 is 9. The expression now reads 5 + 8 * 3 - 9.**Division**/**Multiplication**: Multiplying 8 by 3 gives 24. The expression becomes 5 + 24 - 9.**Addition**/**Subtraction**: Finally, 5 + 24 equals 29, and subtracting 9 yields 20.

Following the BODMAS sequence ensures that the expression is evaluated correctly, and the result is 20.

While the BODMAS rule is widely used in many regions, particularly in the United States and the United Kingdom, BIDMAS is the counterpart acronym mainly employed in the United Kingdom. BIDMAS stands for **Brackets**, **Indices**, **Division**/**Multiplication**, and **Addition**/**Subtraction**. The key distinction here is the use of the term "Indices" instead of "Orders."

**Brackets**: As in BODMAS questions, the first step is to address any operations within brackets, beginning with the innermost set.**Indices**(**Orders**): The term "Indices" refers to operations involving powers and roots, similar to the "Orders" component in BODMAS. This step involves evaluating any exponentiation or square root calculations.**Division**/**Multiplication**: Like in BODMAS, this step requires division and multiplication operations from left to right.**Addition**/**Subtraction**: The final step involves addition and subtraction, again performed from left to right.

To better comprehend the BIDMAS process, let's revisit the example we used earlier:

**Example**: Solve the expression 5 + 8 * (12 รท 4) - 32.

**Brackets**: As before, 12 รท 4 equals 3, resulting in the expression 5 + 8 * 3 - 32**Indices**: The square of 3 remains 9. The expression reads 5 + 8 * 3 - 9.**Division**/**Multiplication**: Multiplying 8 by 3 still gives 24. The expression becomes 5 + 24 - 9.**Addition**/**Subtraction**: Finally, 5 + 24 equals 29, and subtracting 9 yields 20, just as in the BODMAS rule approach.

BODMAS and BIDMAS origins date way back to the early development of mathematical notation. These rules evolved over centuries as a response to the need for standardized procedures in mathematical calculations. While the exact inception dates remain unclear, BODMAS gained prominence in various countries, including the United States. At the same time, BIDMAS emerged as its counterpart in the United Kingdom. Both acronyms are rooted in the need for a consistent order of operations to prevent mathematical ambiguity and ensure accurate results. Over time, these rules have become fundamental pillars of arithmetic and algebraic problem-solving, serving as indispensable tools in mathematics education.
