Why is the last equation on the shirt correct?

• Since the person has no head and therefor no eyes, he cannot see what the shirt say so it doesn't matter. It just doesn't matter....

• If the shirt is yellow, it would make sense that the print should be in black, this is the Charlie Brown Effect

• It makes no sense, 1 + 1 does not equal ten and 11 + 1 cannot = 100

• 11 = 3 & 1 = 1, so that line = 4

  100 is 0(1) +0(2) + 1(4) = 4
