The HP 11C stands out as a mid-range programmable scientific calculator that includes notable enhancements over earlier models such as the HP 33E/C. Key advancements include a built-in random number generator and a backspace key for correcting entries one digit at a time. Additionally, the calculator features hyperbolic and inverse hyperbolic trigonometric functions along with essential statistical tools such as combinations and permutations for probability calculations.

A significant highlight of the HP 11C is its impressive programming capabilities, which allow users to implement label addressing (0-9 and A-E), nestable subroutines up to four levels deep, execute eight conditional tests, utilize increment/decrement loops, and operate two flags. The customization feature enabling users to redefine specific keyboard keys adds to its versatility.
