Hey, CPhill (or whoever reading this), remember that 1-100 with only 2,0,2,1 question I posted? Well, I have gotten some progress on it...

Could you possibly fill in ANY of the empty spots, please? Thank you so much!

I remember doing one of these in 4th grade but with 4,4,4 and 4 instead of 2,0,2 and 1.

Oh, that's cool :). Earlier this school year, we did this exact same assignment with 1234 which was much, MUCH easier than this..

Very difficult to fill in many of the  70s  or 80s  (at least that's what I found)

 

floor (sqrt (2)  /.2  )  *  10    =  70

 

 That's about all I've got right now......maybe I'll think of some more.....!!!!

CPhill, what about $71 = \lceil {\frac{\sqrt{2}}{.2} * 10}\rceil$?

my math teacher said about 90 are possible this year with his rules, he himself getting only about 85. I've got around 81, I think..

Unless I mis-counted....I think you  now have 83....you gave your math teacher a run for his money.....!!!

floor [(sqrt (21))^(2 + 0!)]   =  floor [ (21)^(3/2)]    = 96

 

ceiling  [ (sqrt (21))^(2 + 0!)  = 97

 

Now you have as many as your teacher.....LOL!!!!
