Agree completely. Old school calculator is wrong, but why? Pemdas wasn't really big in school curriculums until around the turn of the century, but the order of operations existed at the previous turn of the century, and should operate correctly on every digital calculator ever made...
The ad filled app sucks for sure, but it is correct in this case.
There's 4 levels to PEMDAS, not 6.
Also,
an actual PEMDAS Solver:

I looked and it's actually wrong. With the exception of MathGPT, I haven't found any e-calcs which do it correctly.
No, it's right. The e-calculator is wrong.
Yes, they should - welcome to what happens when programmers don't bother checking their Maths is correct when writing a calculator app (hence why I wrote the thread I linked to above).
Think of it like this: if you wrote it as a fraction instead of using the divide symbol, the implicit multiplication would only make sense if both were in the denominator.
