The original TI-30 was notable for its very low cost for the time, around US$25. This was much less than the retail prices of other scientific calculators of the era; for example, Hewlett-Packard's cheapest scientific calculator at the time was still well over $100.

The HP-25 was introduced as a cheaper (US$195 MSRP) alternative to the ground-breaking HP-65. To reduce cost, the HP-25 omitted the HP-65's magnetic card reader, so it could only be programmed using the keyboard ...
The HP-25 was a smaller, cheaper model of a programmable scientific calculator without magnetic card reader, with features much like the HP-65. The HP-41 C was a major advance in programmability and capacity, and offered CMOS memory so that programs were not lost when the calculator was switched off.
To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is: 50 / 100 × 40 / 100 = 0.50 × 0.40 = 0.20 = 20 / 100 = 20%. It is not correct to divide by 100 and use the percent sign at the same time; it would literally imply ...

These calculators use a parenthesized infix calculation system called "Algebraic Operating System" (AOS), where, compared to the postfix RPN system used ...
