What is the value of this expression?

Not sure if this is correct or not but my answer is 48
These were my steps:
2(6+(12divided(3+1)-1
2x6=12. 3+1=4 4-1=3
12divided by 3 =4
So now all we have are 12 from (6x2) and 4 from 12div. By3
Then we multiply 12 with the 4 which =48
Hope that helped and made sense.

What can we do about it

So confused right here i need it to be more clearer
