Physical calculator or application calculator?

[Roberto]

We always have some calculations to do everyday which is why calculators are very important. It's not possible to calculate everything off heart because it's going to be too hard to do. It's why we have both physical calculator and applications calculator we have in our phones.

Which one do you prefer to use?

It's been over 20 years I used calculator device. It was when I was still in college and partly in high school too. Before I was done with school, I've already stopped using it. Anything I want to calculate now, I make use of the one in my iPhone 13 Pro Max.
