Introduction to the tool and how to use it

Work out the usual percentage questions from two numbers, with as many rows as you like in one go.

How to use:
1. Enter one pair of numbers per line, separated by a comma or space, e.g. 25,200;
2. Pick a mode (what percent, percent of, change rate, increase, decrease);
3. Hit Run and the table shows both the formula and the result - copy it or export it as CSV.

Change-rate mode marks up, down or flat; rows with only one number or a zero divisor are skipped with a notice.
