On Wednesday I took the Math Olympiads and am 99% sure I got 5/5.
On Thursday I took Continental Math League and I MISSED A PROBLEM! The problem: Calculate AB+BA (base 12) and convert it to base 10. Somehow, I got 275 when it’s actually 273. [tex]AB_{12} + BA_{12} = (10 times 12^1 + 11 times 12^0)+(11 times 12^1 + 10 times 12^0) \ = (120+11)+(132+10) = (131)+(142) = 273!!![/tex] ARGH! I guess I’m not a national leader anymore…:-(
I too missed a CML problem. The newspaper delivery was IRRATATINGLY STUPID. Im not a national leader anymore
