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. A digit and its value are different: the digit tells how many units of that place are present.

Order changes the resultno bracketsmultiply before adding: 90bracketsbrackets first: 378

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.
