When eval an equation does it follow the PEMDAS rules?
For example: 2.0-1.0-3.0*6.0+5.0*4.0 when evaluated equals 3.0 when evaluated by python. To me that doesn't seem correct, I get a much larger number than 3.0
When I evaluate in python eval("6/2*3") it should equal 1 but in python it equals 9.
So anyone give me an idea on how to get eval to follow the PEMDAS rules?

It does follow PEMDAS rules.
Never doubt Python's adherence to math rules.
6/2*3 equals 9 on:
:D
that is because PEMDAS works like this: P, E, M and D, A and S So according to PEMDAS:
6/2*3
is(6/2)*3
That's because multiplication and division are the same rank.

Also, you stated that 2 - 1 - 3 * 6 + 5 * 4 = 3 according to Python.
That's absolutely correct.
Face palm!
Thank you again!

As a side not, ask someone what 2+2*2 equals. Most people will say 8 instead of 6 lol. I've even got my teachers with it lol.
