Desing a circuit that sums 2 binary numbers(of 2 bits), with 2 bits of output.?

Question

I worked out this:
x1,x2 = are the bits of the first binary numbers(x1 the MSB and x2 the LSB)
x3,x4 = same but with second number.
y1,y2=are the sum, sames as above, but this represents the output.

&= is the "xor" logic gate, and # is "not, the inversor.
-----------------------
x1----\
____ & ----I-----y1
x2----/___ I
_________I%
x3----\ ____\
_____& ----OR------y2
x4----/

ignore the "_________" they mean nothing.

There's a pretty good article on adder circuits at

You might check it out to see if your circuit is about the same ☺

Answer 2

by using fact the sq. root of two is an irrational style, the binary illustration has a limiteless style of 0s and 1s. yet merely by using fact the numbers of each and every are the two countless would not unavoidably advise you could no longer evaluate them. as an occasion, real numbers have a extra suitable "order of infinity" than organic numbers. i don't understand adequate math to understand how order of infinity could stick to to that end, yet i do no longer think of you could anticipate the numbers of 0's and a million's are comparable.
