The pattern behind it: Large numbers and operation order
Group digits by place value, then do brackets and multiplication or division before addition or subtraction.
In this one. Dividing by 700 means dividing by 7 and by 100. Cancelling zeros alone is safe only when place value is preserved.
How to spot it
Two numbers to add with carrying, several numbers to put in order, or a sum mixing addition, multiplication and brackets, all point here.
Common mistake
Children forget to carry a ten into the next column, or compare digits from the left without first checking the numbers have the same number of digits.
