7-31-2018 Going to pick up 6 calculators from someone on Facebook for $40 with manuals and cases. The manuals are pretty thick so I'm not sure if I'm going to list the items with them.
Hp 48g - regularly sell on Amazon for $80
Hp 17bii-$25
Hp 33s-$50-$75
Hp18-$100
Hp28c-$75
Casio fx 9750g plus- $20
For those of you who don't know hp calculators are popular because they use reverse polish notation that engineers and math nerds prefer.
Going over this I'm thinking this is crazy roi.
Bankroll

818.20 (reverse polish notation)
