Page 2: Detailed Explanation of BODMAS/BIDMAS

This page provides a comprehensive breakdown of the BODMAS (or BIDMAS) rule, explaining each component and its significance in equation solving.

Definition: BODMAS is an acronym that stands for Brackets, Orders (or Indices in BIDMAS), Division, Multiplication, Addition, and Subtraction.

The rule is explained step-by-step:

1. B - Brackets: Always solve the expressions within brackets first.
2. O/I - Orders/Indices: Calculate any exponents, square roots, or other orders.
3. D - Division: Perform any division operations from left to right.
4. M - Multiplication: Complete multiplication operations from left to right.
5. A - Addition: Add any remaining terms from left to right.
6. S - Subtraction: Subtract any remaining terms, again from left to right.

Vocabulary:

• Indices: Another term for exponents or powers.
• Square roots: The inverse operation of squaring a number.

Highlight: The BODMAS rule is essential for solving complex equations and ensures consistency in mathematical problem-solving across different educational levels.

This page emphasizes the importance of following the BODMAS sequence to avoid errors in calculations, especially in step by step bodmas equation solving examples.

Page 1: Solving a Complex Equation Using BODMAS

This page demonstrates the step-by-step application of the BODMAS rule in solving a complex equation. The example equation is:

36 ÷ 3 × 9 + 3² - 13 × 9 = 90

The solution process follows the BODMAS order:

1. Brackets: There are no brackets in this equation, so we move to the next step.
2. Orders: 3² is calculated first, resulting in 9.
3. Division and Multiplication: 36 ÷ 3 = 12, then 12 × 9 = 108, and 13 × 9 = 117.
4. Addition and Subtraction: The final steps involve adding and subtracting the remaining terms.

Example: The equation 36 ÷ 3 × 9 + 3² - 13 × 9 = 90 is solved as follows:

1. 36 ÷ 3 × 9 + 9 - 117 = 90
2. 12 × 9 + 9 - 117 = 90
3. 108 + 9 - 117 = 90
4. 117 - 117 = 90
5. 0 = 90

Highlight: This example illustrates the importance of following the BODMAS rule to arrive at the correct solution. Without proper order, the result would be incorrect.
