Student A and C misconception in subtracting 2 digit number with another 2 digit number

# data[].attributes.body
Student A firstly
- starts subtracting for the tens place first and it's not a good habit if we're looking at the algorithm unless he has already checked that there is more on top for the ones place
- mistakenly takes the tens remainder and subtracts the ones remainder
- May need pictorial manipulatives.
