A mathematical limerick is truly a thing of beauty. \(\displaystyle{\frac{12 + 144 + 20 + 3\times\sqrt{4}}{7}} + 5\times11 = 9^{2} + 0\) A dozen, a gross, and a score Plus three times the square root of four Divided by seven Plus five times eleven Is nine squared and not a bit more.

Take a two-digit base-10 number where the digits are represented by ab. This number is equal to 10a + b and the sum of its digits are a + b. The difference between the number and the sum is 9a, which is divisible by three. So a + b is divisible by three, if and only… Read More »
“The trick to education is to teach people in such a way that they don’t realize they’re learning until it’s too late.” — Harold Eugene “Doc” Edgerton (April 6, 1903–January 4, 1990), a.k.a. “Papa Flash”, photographer
The only 3-digit answer is \(544_9 = 445_{10}\). However, there are answers in other bases: \(211_3 = 112_4\) \(322_5 = 223_6\) \(433_7 = 334_8\) \(544_9 = 445_{10}\) Are you seeing a pattern here? Does the pattern extended to bases higher than 10? Does \(655_{10} = 556_{11}\)? Does \(766_{11} = 667_{12}\)? Cheating a little bit by… Read More »
