Deliberate column subtraction mistakes
<p>A worksheet with a set of 8 column subtraction calculations, each with a different deliberate mistake (all except number 5, which is correct).</p>
<p>I searched the internet for something like this and couldn’t find one. So I had to make it.</p>
<p>It’s a PDF, I’m afraid, since it was easier for me to write them out by hand than work out how to do it on a computer.</p>
<p>There is now an answer sheet.</p>
