Inside the parens first, so it becomes 2 + 5*3

Then tou do multiplication before addition, so 2 + 15

Then addition, so 17

Yeah I know that. But I was feeling confused as to why it was here. That’s why I was feeling trolled, because it made me doubt basic math for being posted in a memes community.

  Because OP posts garbage to all the meme communities.

  They did the joke wrong. To do it right you need to use the ÷ symbol. Because people never use that after they learn fraction, people treat things like a + b ÷ c + d as
  
  a + b ----- c + d
  
  Or (a + b) ÷ (c + d) when they should be treating it as a + (b ÷ c) + d.
  
  That’s the most common one of these “troll.math” tricks. Because notating as
  
  a + b + d - c
  
  Is much more common and useful. Do people get used to grouping everything around the division operator as if they’re in parentheses.

  Alternatively, the poster calculated the wrong answer, thus assuming this guy was wrong.
