Nice quiz, but a dodecahedron has 12 faces!

A quintillion is 1000, not 100, quadrillions.

In the UK, we use the name 'Trapezium' instead of Trapezoid. Please allow this to be an answer.

You should really accept "brackets" and "parentheses" for "groupings". I've never heard it called "groupings" ever

Not all fractals have infinite perimeter.

Yeah this hint is way too vague to yield the answer except by guessing -- "infinite perimeter" is just not the thing that characterizes fractals, and my mind went to a million other places first. Maybe a hint about self-similarity at every scale, or something along those lines, would be better.

Please accept British spellings such as 'millimetre', and brackets should also be an acceptable answer.

An angle between 90 and 91 degrees is obtuse, too

When you think you're clever and you write dodecohedron... so sad.

Accept Brackets as well. Also, miles per hour & metres per second question would have speed(or even velocity) as more apt answer than rate. Rate is too broad of a term to just be defined by distance per time.

why wont it accept trapezium
