There’s nothing wrong with calculators

There is if you're talking about calculators on phones, etc. Almost all of them give wrong answers to order of operations questions because the programmer didn't bother checking their Maths first. It's so bad that the Windows calculator in Standard mode says 2+3x4=20. Stick to name brands like Sharp and Casio. They have money invested in the success of their products, so they take more care to make sure it's correct!

I haven't sent anything to anyone that wasn't spell checked in more than a decade. So, ya it's going to be a weird future where you just choose the comment you want to respond to and AI fills it out for you.
