When I was in Six Grade Pocket Calculators were being advertised in Popular Science Magazine for 600 dollars. I saw a better calculator for 3.50 in Dollar General. The cheap calculator had a memory that could store ten different numbers, sign, cosign, tangent, cotagent, and keys that let you choose what power or root you wanted.
