Yes, this behaviour depends on whether your specific model of calculator uses a higher priority for implicit multiplication.
Implicit multiplication being higher priority is a nice shorthand for reducing number of brackets when writing simple fractions without the proper typesetting of the horizontal line.
Because most mathematical works don’t have this typographical limitation, such statements don’t appear often. When they do appear, it’s just important that the convention within one text is consistent (and hopefully explicitly mentioned).
They seem to be saying that however a calculator would calculate it is ipso facto correct.
Which is odd because I had at least one, maybe more, teacher show us this as a reason not to blindly trust your calculator

Different calculators will disagree when u type the question in BTW. Its a typography problem created by lazy mathematicians and algebra
