Explanation: First, solve the Vinculum/Bar (6 + 2 = 8). The expression becomes 10 - (8 - 8). Then solve the bracket (8 - 8 = 0). Finally, 10 - 0 = 10. Correction: Re-reading the question, the bar seems to be over 6+2. Let's re-solve. Expression is 10 - (8 - 6+2). Bar first: 6+2=8. Expression becomes 10 - (8-8). Bracket next: 8-8=0. Result is 10-0 = 10. It seems none of the options match. Let me re-evaluate the question's intent. Often, a bar is placed to change the normal order.

The full form of BODMAS is Brackets, Orders, Division, Multiplication, Addition, and Subtraction. This is the exact order you must follow to solve any mathematical expression correctly.
Here are the rules:
Division and Multiplication have the same priority, so you solve them from left to right. Similarly, Addition and Subtraction have equal priority and are also solved from left to right.
Solving BODMAS questions is easy if you follow these four simple steps:
Example: Solve (5 + 7) × 2 - 3²
BODMAS and PEMDAS are just two different names for the exact same rule of solving mathematical expressions. They lead to the same answer.
Here’s how they compare:
The order of M and D is swapped, but it doesn't matter because they have equal priority and are always solved from left to right.
Certainly! Here are a couple of solved examples.
Example 1: 40 ÷ 5 + 3 × (10 - 4)
Example 2: [20 - {12 - (5 + 2)}]
