(Print)
complex numbers is actually geo problem
euler totient function
maximize/minimize algebraic expression
roots of unity
Algebra or Geo problem is secretly a Combo problem
(fat expression)^2 >= 0
cauchy schwarz
incorrect problem
"find f(0)" or "f(1)"
"Alice and Bob play a game"
"triangle ABC"
"how many ways..."
cards/dice/chess
lifting the exponent
random trig when its totally unnecessary
"coord bashable"
at least two circles
self-similar expression
burnside's lemma not strictly needed
average/ev problem
hockey stick
problem difficulty out of order
answer less than 10
log base variable
calculus bait
trivial by modular arithmetic
off by one because edge case
jumping on coordinate plane
off by factor of two because sillies
ugly exact form
am gm hm qm
3D tangent sphere
one line AOPS solution
draw at least 3 imaginary lines
new random symbol in problem statement
bash to win
copy pasted problem
probability is geometry
trivial by semi-obscure identity
"find largest integer satisfying..."
