Its because its
2+5×(8−5)
My calculator app automatically added it when typing in what was I’m the image and “2+5×(8−5)” does equal 17
It’s absolutely the fault of the person making the social media media post for not writing it properly and confusing people

It’s not the Education system, it’s people not remembering what they were taught

No it isn’t. It’s 2+5(8−5). Different expression, but in this case co-incidentally the same answer. Preface the first 5 with a Division and you get different answers.
My calculator app
Was written by a programmer who didn’t check the rules of Maths first. The only e-calc I’ve ever seen give the correct answer is MathGPT
not writing it properly
Except it is written properly, as per Maths textbooks

The multiplication is implied and has been part of the standard mathematical notation for far longer than any of us have been alive.

No it’s not. It’s explicitly The Distributive Law, a(b+c)=(ab+ac). There is no Multiplication
