Domande frequenti

How do I add 10% to a number?

Use “What is X% of a number?” to find the 10% and add it to the number. Or multiply the number by 1.10.

Is 20% off and then another 10% off the same as 30%?

No. It comes to 28%, because the 10% applies to the price that was already discounted.

Can the change be negative?

Yes. When the final value is lower, we show the drop as a percentage.
