Your favorite thing about redstone: logical redstone and making traps
A build you have made which demonstrates redstone knowledge (This is your trial build):a 8 bit adder pretty compact
Explain what your build does in detail: it XORs A and b than ANDs then which im pretty sure is an ISor than it has a OR and takes the carry and sends it up to all the upper layers doing the same things and gets the awenser
You need to pass the Quiz before actually applying. Concentrate and take your time on the next try - Feel free to reply with the new results.
Also, your trial build is not sufficiently advanced. The bar for trial builds is at or above the level of a 4 Bit ALU. Please respond with a new build if/when you decide on one.
