my pro

I have a project today and i have to implement it before the presentation
my project is ALU 4 bit using Mux and Adder i want it in multisim to implement it in board and report for it
the table:
s1 s0
0 0 add
0 1 subtract
1 0 increment
1 1 decrement
i have to use 8×1 mux because this is just in the lab we don’t have 4×1
