"More Than" should be accepted for "Greater Than," and "Summation" should be accepted for "Summation Notation" as well.

I always thought it was "substract" (and I said it like that as well ^^). You should accept "summation" for Sigma and "difference" or "variation" for Delta.

Whew! Tough to make a quiz like this when so many symbols have multiple definitions. In my day, x was any unknown, while k, l, m, or n were typically integers, theta was often the polar angle, and ~ was simply "approximately equal to." It was fun to try to run through this though, even though I missed ~.

"approximately equal to" is usually ≈. The symbol ~ has a ton of meanings depending on the field (geometry, set theory, statistics, linear algebra, physics, etc)

^ is not "Exponential Function". It is "to the power of"

"^" may be seen as the vector product symbol, "#" as a cardinal and "[]" as the integer part of a number. It's very innacurate....

% can also stand for modulo/modulus or remainder.

~ also means Approximately or About.
