These 100 bits of math trivia range from I got that to What???!!!. For math nerds and others who appreciate unusual trivia or want to learn something.

**1.** In 1988, Nicolas Slonimsky (1894-1995) invented a method of beating a different rhythm with each arm–created a new composition by identifying each note in Beethoven’s Fifth Symphony with a number, and then playing the square root of each note.

**2.** The symbol for infinity (∞) was used by the Romans to represent 1000.

**3. **All palindromes with even number of digits are divisible by 11.

**4.** The earliest evidence of a numerical recording device is a section of a fibula of a baboon, with 29 visible notches, dated to about 35000 BC, from a cave in the Lebombo mountains on the borders of Swaziland in Southern Africa.

**5.** The number 365 is equal to the sum of three consecutive squares and two consecutive squares in which the five squares are also consecutive.

365 = 10^{2} + 11^{2} + 12^{2} = 13^{2} + 14^{2}

**6. **

Meanwhile, my Google Home Mini can’t find the square root of 144. Bummer!
