You change this in formula:

I know it wasn't saked, but I recommend getting an RPN calculator, as it is more effective for entering numbers - here is how:

CAS input mode:
 1 (
 2  1
 3  *
 4  2
 5 )
 6 /
 7 (
 8  1
 9  +
10  2
11 )
12 Enter

RPN input mode:
 1 1
 2 Enter
 3 2
 4 *
 5 1
 6 Enter
 7 2
 8 +
 9 /
