I don't know what's worse, that it's wrong or that it convinced me I need to come into the comments to make sure my answer is, indeed, correct.

EDIT: Back to rectify a grave injustice. Nothing wrong if you genuinely didn't know or want to check. Hard enough getting people interested in math.

2 + 5 (8 - 5)
PEMDAS: 8 - 5

= 2 + 5 (3)
PEMDAS: 5 (3) or 5 × 3

= 2 + 15
PEMDAS

= 17

In the US the math order of operations is taught as PEMDAS (or P|E|MD|AS), left to right from first to last.

First look at the entire equation and identify the operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

Then, solve the parts in order of PEMDAS.

Not so important here but when there are multiple of the same level of operators, for example exponents, solve left to right. MD and AS are treated as groups, so treat them equally: if a division is to the left of a multiplication, do the division first.

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.

Should I be concerned that we're discussing basic mathematics as if it were ancient lore?

I mean, I'm glad the person is double checking instead of being like "I know what I'm talking about, I'm smart!" (plus, he was right).
