Easy includes increases and decreases. From 40 to 50 is a 25% increase. From 50 to 40 is a 20% decrease.
Medium and hard ask you to type the percent change, including a minus sign for a decrease.
Each round is ten questions and 30 seconds. A streak of three adds half the points. A streak of five adds the full points again.
From 40 to 50: the change is 10, and 10 ÷ 40 × 100 = 25.
