Chris posted this one over on his blog, so I thought I'd give it a try - I am pretty good with addition/subtraction in my head - looks like I did alright:
Bugger.. I got 1 wrong and it doesn't say which one.. "I should go buy a gun and shoot myself" is what I would have said in 8th grade.
Ahh.. ok.. 5.5 squared I read to quick.. thought it was asking for the square root of 5.5 which would be no where nead 30.. Guess I don't need to buy that gun..
Math sucks.. :-)
actually - 5.5 squared is something like 27.5 - maybe you missed the mode/median/standard deviation question.
My math is bad. :(
Jeez.. I was thinking square root I guess.. oh well this post is 2 years old almost.. no big deal.
