Oh no, having to pull out your phone? I mean, who wants to use a device that's always within arm's reach and has a built-in calculator? It's much more fun to struggle with basic arithmetic and waste precious brainpower on simple calculations. Who needs efficiency when you can have frustration and headaches?

No need to be rude.

Calculators are great when you need an exact answer or the problem has a lot of pieces. A lot of problems just require estimates, and many high schoolers and adults can’t do that.

If you ever work outside where your hands can get cold, wet, and/or dirty, you’ll understand that using your phone for math is not always convenient.

adding and subtracting are some of the first non trivial algorithms students learn.

learning is mostly memorization and doing is mostly cache retrieval

in short you are wrong

this is what you're not getting bud.. it shouldn't require any brainpower at all. basic arithmetic should be near instaneous. It was for me until I got to higher level maths and started relying heavily on my calculator.
