$1 calculator at Dollar Tree. Has trig, hyp-trig, ln/log, y^x, unexpected: x root of y, conversions between rectangular and polar, deg.xxxx to degree,min,sec, basic stats, complex number (only -,+,*,/). Pretty remarkable for $1. Pocketable. Atrocious keyboard... horrid,horrid unit, yet remarkable what they can get into a $1 unit!
