*headscratch* Multiple people got 47? I'm struggling to figure that
out. If they interpret the first part as multiplication (3*2 => 6),
that would get 26*2 => 52; if they don't understand the square
rooting, they'd probably just give up; if they ignore the parentheses,
that could give 9 + 20*2 => 49; but I can't come up with 47.
