This HP classic features a unique ?Collector?s Edition? script, making it a great gift for collectors and engineers alike. The HP 15c offers users a high-end and portable, scientific calculator with programmable functions and built-in support for complex numbers, matrix math, numerical integration, and root solving, which makes this device one of the most capable calculators HP has ever made.\u003c\/p\u003e\n\u003cp\u003eThe new HP 15c maintains the same intelligent design as the original but touts up to 100x faster processing speed. Its compact size and lightweight metal frame allows users to conveniently carry the HP 15c from meeting to meeting. Unlike other scientific calculators, the HP 15c also offers an intuitive, horizontal interface, just like the original. \u003cbr clear=\"left\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProgramming capabilities include: conditional and unconditional branching, subroutines, flags, and editing.
