Complex Calculator
It’s easy to forget, but there was a time before everyone had a calculator in their pockets. Back in the old days, they were the size of a brick and could only do basic math. But let’s be real; those old calculators were like trying to text with a flip phone. It was doable but definitely not convenient.
They were also so fragile; one wrong button press and you’d have to start all over again. Remember the calculator watch or the calculator pen? It was like you were a secret agent, quietly solving math problems without anyone noticing. Those old calculators may not have been the most advanced technology, but they definitely had some charm.
