Question

27-12+4. Please read description.

Description:
This is kinda embarrassing to ask...but I keep getting different answers!
Some calculators say it's 19, but when I work it out, I can only get 11!.

So I add 12+4 to get 16.
Then I subtract from 27 and get ll.
Please help and explain what I'm doing wrong please help. I use PEMDAS btw

Explanation:

Use MathPapa it is AMAZING! it will also give you a step by step if you want, and it is Free! (The answer is 19 btw)

27−12+4

When using Pemdas you do addition or subtraction in the order that it comes (so which ever is first). Same with multiplication and Division
