Saif subtracts nothing from a whole number and ends up with nothing!
We have been doing some column subtraction in 6W. It’s a complicated method with lots of borrowing and exchanging to be done. Sometimes though, it’s the easier bits of the calculation that you get wrong by making a silly mistake.
Check out this picture – can you tell what is wrong with the calculation.
Saif spotted his own mistake and shared it with the class to remind us all that taking away 0 does not leave you with nothing (unless you started off with 0 in the first place)
