Shouldn't it be 83?
(27+15)^2 - (63-22)^2 = 42^2 - 41^2 (42+41)*(42-41) = 83*1 = 83.

So, adding 42 and 41 was my downfall! Ha!!
Thanks for the heads up!
I've edited my solution.
Kudos for you!!

Cheers,

Is that you, Karaan?
Good catch!! I changed the number in my solution, but not in the original question.
My bad.

Kudos for you!!!
