what is 1 + 1 x 1 + 1
do you use the PEMDAS rule and get three or do it in order and get four?

I think you get 3 either way.

According to PEMDAS,
1+1x1+1=1+1+1=3
doing as it is,
1+1x1+1=2x1+1=2+1=3
the answer is 3 either way, but the real difference comes during the exams. The use of the second method fulfills your dream of sitting in the same class for two years.

You follow PEMDAS. So it breaks down as follows.
1+1x1+1=
1+1+1=
3

If you did it in order you would get 3,
1+1 = 2 2 x 1 = 2 2 + 1 = 3
And that is the same answer you would get if you did it correctly, which is by multiplying first (1 x 1) = 1, 1 + 1 + 1 = 3
The only way to get 4 would be
(1+1) x (1+1)
2 x 2 = 4

1 + 1x1 + 1 = 3
Do all multiplications first - 1 + 1x1 + 1 = 1 + 1 + 1 = 3
If you had written
(1+1) x (1 + 1) the you would do the additions inside the ( ) first and then multiply . You'd get 4.

Either way the answer is 3, PEMDAS Rule or not.

Always PEMDAS, always. So its 3.
But even if you ignored PEMDAS you would get 3 in this case.

Written as it is, the answer is 3. Multiplication is always performed before addition.
