Subtract the two numbers: `difference = |A – B|`
Find the average of the two numbers: `average = (A + B) / 2`
Divide the difference by the average: `difference / average`
Multiply by 100: `percentage difference = (|A – B| / ((A + B) / 2)) × 100`
Use the formula: `Percentage Difference = (|A – B| / ((A + B) / 2)) × 100`
