OTD in 1972, @HP debuted the HP-35, the 1st handheld pocket calculator with scientific (trigonometric and exponential) functions. It was 5.8 x 3.2 in. “We figured, in the first year, if we could sell 10,000 calculators, we'd break even. We sold 100,000." https://t.co/X1ZhuMJLq5 https://t.co/xqWhZ1cLmy — PolitiTweet.org
