Five concrete examples of the Binary Subtractor in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Subtracting binary values for homework
The task: Subtracting binary values for homework. You start from a minuend and a subtrahend written as binary numbers with only 0 and 1 digits.. The tool returns the binary difference, with every borrow marked in the working., giving you a correct difference, or a note when the result would go negative for unsigned input. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Checking a full subtractor truth table result
The task: Checking a full subtractor truth table result. You start from a minuend and a subtrahend written as binary numbers with only 0 and 1 digits.. The tool returns the binary difference, with every borrow marked in the working., giving you a correct difference, or a note when the result would go negative for unsigned input. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 3: Finding a bit mask complement by hand
The task: Finding a bit mask complement by hand. You start from a minuend and a subtrahend written as binary numbers with only 0 and 1 digits.. The tool returns the binary difference, with every borrow marked in the working., giving you a correct difference, or a note when the result would go negative for unsigned input. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 4: Verifying unsigned bit differences
The task: Verifying unsigned bit differences. You start from a minuend and a subtrahend written as binary numbers with only 0 and 1 digits.. The tool returns the binary difference, with every borrow marked in the working., giving you a correct difference, or a note when the result would go negative for unsigned input. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 5: Tracing a borrow in a digital logic lab
The task: Tracing a borrow in a digital logic lab. You start from a minuend and a subtrahend written as binary numbers with only 0 and 1 digits.. The tool returns the binary difference, with every borrow marked in the working., giving you a correct difference, or a note when the result would go negative for unsigned input. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
A Full Worked Example
Input: 1010 minus 0111
0011, because a borrow moves across two columns to finish the difference.
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
Frequently Asked Questions
What if the answer would be negative?
The tool reports it for unsigned input, and you can reinterpret the bits as two's complement for a signed reading.
Do both numbers need the same length?
No - the shorter operand is padded with leading zeros before any borrow is applied.
How are borrows shown?
Each borrowed bit is marked in the column working so you can follow the chain by hand.
Is my input stored?
No - subtraction runs in your browser and nothing is saved.
