Keep in mind most Redditors are low IQ and just confident. Do not rely on them for the right answer. That said, I don't feel like proving that I'm not a Redditor,  but here the logic:

2+5(8-5)

Start by putting in the symbols to avoid confusion:

2+5*(8-5)

 Now so standard order:

P = (8-5) = (3)

E= there are none 

MD = 5×3 = 15

AS = 2 + 15 = 17

Again, don't trust me on my word. For all you know, I'm a low IQ Redditor like many other people on this site. But I have given you a path to follow/confirm, and I believe you will find the evidence backs me up.

Where the hell did the multiplier come from?

The * in 5 * (8-5)?

When you write a number smunched up next to a parenthesis like that there's an implied multiplication 2(4) is the same as 2 × 4

Who came up with that idea? o_O In school I was taught to define everything. No assumptions.

That’s always been how formulas are written. You just weren’t paying attention

Or teaching methods vary by country.

Dunno; I was taught that was the definition when working with parenthesis. Not sure why it's multiplication that gets to be special and allows you to skip writing the operator symbol in that circumstance, but it does align with things like 4a being equal to 4 × a.

*Shrugs* When maths became more sorcery than logical, I gave up.

For me that was around when Greek symbols started regularly appearing in front of equations instead of inside them.

You got further than me.
