Could you possibly fill in ANY of the empty spots, please? Thank you so much!
+539 I remember doing one of these in 4th grade but with 4,4,4 and 4 instead of 2,0,2 and 1.
+129852 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.....!!!!
+36 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..
