A Rare Math Coincidence
Riddle:
Which two whole positive numbers give the same result when you subtract one from the other as when you divide one by the other?
Answer:
Answer: 2 and 1. Explanation: 2 – 1 = 1 and 2 ÷ 2 = 1. To solve: A – B = A ÷ B → Multiply both sides by B: A(B – 1) = B². Try B=2 → A=4. So 4 and 2 also work. But 2 and 1 is the simplest.
