AND from NAND

Y must be A AND B. Prefer NAND + NOT if you want the par score.

Learn first

AND says yes only when both inputs are on. NAND is AND followed by NOT — so undo the NOT to get AND back.

A NAND gate gives 0 only when A and B are both 1; every other time it gives 1. That is exactly the opposite of AND.

So an AND is just a NAND with its answer flipped. You already know how to flip a bit from lab 1: feed the NAND's output into another NAND with both pins tied together.

Try this

Two INs (A and B) into a NAND. Its output into a second NAND with both pins tied to that wire (a NOT). The second NAND's output is Y. Try all four combinations: Y should be 1 only for A=1, B=1.

Stuck?

NAND(A,B) into a NOT, or drop the AND macro (same cost).

Par is 2 NAND. Using more still passes; fewer is just neater.

Statuspass the lab first

One grant per lab per wallet, materials only — WFR is earned by mining verified dies, never given away. The server re-checks your circuit before signing.

Etch it as a die (optional)

Turn this circuit into a verified die you own. It burns 0 NAND — the grant covers it.
