I was just watching a local adoption of the show "Are you smarter than a 5thgrader?" and there was an old lady playing. She struggled to answer a question "Find a way to express 10 with five 9". While she figured out (99 - 9) - 9/9 = 10, I figured out 14 more ways to do it?
How many ways can you guys find?
P.s. I used derivatives, trigonometry, logarit ...[text shortened]... ere definitely are more ways, but the number I gave is how many I found during the question.
