The answer given to number 5 is incorrect. While the first answer provides the magnitude of parrot cross banana, it fails to take into account the direction (the result of a cross product is a vector). Though it merely restates the problem using mathematical symbology, the third answer would be the most correct.
But parrots aren't vectors!

The variable types need to be declared.
Here's one~
A mathematician, a physicist, and an engineer were traveling through Scotland when they saw a black sheep through the window of the train.
"Aha," says the engineer, "I see that Scottish sheep are black."
"Hmm," says the physicist, "You mean that some Scottish sheep are black."
"No," says the mathematician, "All we know is that there is at least one sheep in Scotland, and that at least one side of that one sheep is black!"
