This is what happens when math teachers say "there are many ways to solve a problem." Sure, multiplying both sides by π is technically correct in the same way that using a flamethrower to light a birthday candle is technically effective.
The beautiful part? The answer is correct! 1/2 + 1/3 = 5/6. But the journey there is like taking a detour through another dimension where π decides to crash the fraction party uninvited.
That little smiley face at the end is the universal symbol for "I know this is ridiculous but it works and I'm way too pleased with myself." Math chaos agents, unite!
