Pro tips
- • “X% of Y” and “Y% of X” always give the same answer — 8% of 50 equals 50% of 8.
- • Percentage change always divides by the ORIGINAL value, which is why +50% followed by −50% does not return to the start.
- • For discounts, subtract the percentage result from the original price to get the sale price.
