There are only 5 blocks, 1 block: type - and / enter - 1, 3. 2 block: type - NOR Gate / enter - 2,4. 3 block: type - XOR Gate / enter 1,2
4 block: type - Subtractor Gate / enter 1,3 and 2, 4. 5 block: type - Sumator / enter 1,4 and 2,3

There are only 5 blocks, 1 block: type - and / enter - 1, 3. 2 block: type - NOR Gate / enter - 2,4. 3 block: type - XOR Gate / enter 1,2
4 block: type - Subtractor Gate / enter 1,3 and 2, 4. 5 block: type - Sumator / enter 1,4 and 2,3

And what is it that you are supposed to do and what is it that you are asking for assistance with?

Are these five blocks the building block that you are given? Or are they five blocks you are supposed to design?

Are we supposed to know what something like "enter 1,3 and 2,4. 5" is supposed to mean?

 

Yes, this is my homework

It would be helpful if you posted the schematic, the full text of the problem, and stated what you're having difficulty with.
