Correction, your username is Paridoxlife not paradoxlife.
Additionally, please follow the Read Before Posting instructions. You’re supposed to set a warp for your trial build.
Regardless of that - I found the build anyway, and it’s not sufficiently advanced. What you have is a bunch of AND gates wired together to give the “answer” to the multiplication of 6 different pairs of numbers. That is not a 4 bit multiplier.
When you have a new trial build which is at or exceeding the complexity of a 4 bit ALU, please respond to this thread with it (don’t make a new one).
