How do order of operations go on Python?

Question

My question looks like this:

  10-7//2*3+1 

I am supposed to solve the equation.

My answer seems to come out as 8 when using PEMDAS:

First its's 2*3 = 6; 10-7//6+1
second = 7//6= 1; 10-1+1
Third = 10-8 = 8;

But when putting it into python, I get a 2. Why is this so?

It seems the programs order is as such:

first: 7//2=3; 10-3*3+1
second: 3*3=9; 10-9+1
third:10-9+1= 2; 2

I don't get it.

Answer 1

PEMDAS is better expressed as

P   Parentheses, then
E   Exponents, then
MD  Multiplication and division, left to right, then
AS  Addition and subtraction, left to right

So in your expression, the division should be done before the multiplication, since it is to the left of the multiplication. After those are done, then do the subtraction then the addition.
