Ready to print
Start with a ready-made worksheet
Apply the named operator to each column without carrying. Keep every answer at the chosen width, including leading zeroes.
Download the practice pages alone, or include a separate answer key or teacher model. Longer activities may use more than one page.

A fixed width is part of the problem
Every input and answer has four or eight bits. NAND, NOR and NXOR complement only those positions. Leading zeroes remain visible so you can compare one column at a time.
The preview and downloaded PDF use the same questions. Include answers to append a separate key, or download just the student worksheet.
Learning objective
What this activity builds
Apply a logical rule independently to each matching pair of binary digits.
Worked example
Find 1010 XOR 1100 using four bits.
0110.
XOR returns 1 where the two input bits differ and 0 where they match. The first output bit is zero and must remain visible.
Teaching notes
Make the practice count
- Start with one operator and its four-row truth table.
- Compare one bit position at a time.
- Find AND, OR or XOR before taking its width-bounded complement.
- NXOR, also called XNOR, returns 1 when the two bits agree.
