I could ask you "why not", but you'd probably just repeat some drivel you learned in your basic programming class.

Not sure how anyone is passing this. There's either an error in the instructions or in the tests.

As posted below: "Test #3 of testBasics in PHP fails (result is false, but expected is true), which is because of $a2 having 36100 in it, but $a1 has no 190."

This absolutely occurs. Another comment indicates that the arrays have to be of equal length, which would not make the above true. Yet another comment states that each number of A1 must have a matching square in A2, which if true, is not mentioned in the instructions.

I hate shit like this. You guys spend so much effort trying to come up with the most elaborate, confusing problems, that you can't even keep straight what you're trying to accomplish.

Ditto. Broken at the moment.
