There's a wrong answer in the quiz, for 58*62 you have 3472 as the answer, but that is equal to 56*62...
I'd say 58*62 is the more interesting question to ask, because you can answer it easily with the difference of squares (since 58*62 = (60 - 2)(60 + 2) = 60^2 - 2^2 = 3600 - 4 = 3596 ).
The Content Update is out with new quizzes, corrections and a new series has just been launched.
Thanks for the 3k attempts!
I hope Starmpro7 doesn't overtake me.
See you soon :)
