If A denotes '+', B denotes '-', C denotes 'x', and D denotes '÷', then which of the following statement is true?
8A8B8C8B = -48
Let's analyze each option by substituting the given notations:
- Option 1: 8B6D2A4C3 = 15
This translates to \(8 - 6 \div 2 + 4 \times 3\). Following the order of operations (division and multiplication before addition and subtraction), we get \(8 - 3 + 12 = 17\), which is not equal to 15.
- Option 2: 8A8B8C8B = -48
This translates to \(8 + 8 - 8 \times 8\). Following the order of operations, we get \(8 + 8 - 64 = 16 - 64 = -48\). This statement is true.
- Option 3: 9C9B9D9A9 = 17
This translates to \(9 \times 9 - 9 \div 9 + 9\). Following the order of operations, we get \(81 - 1 + 9 = 89\), which is not equal to 17.
- Option 4: 3A3B3C3A3D3 = 4
This translates to \(3 + 3 - 3 \times 3 + 3 \div 3\). Following the order of operations, we get \(3 + 3 - 9 + 1 = -2\), which is not equal to 4.
Therefore, only Option 2 is true. The correct calculation is \(8 + 8 - (8 \times 8) = 16 - 64 = -48\).
