Many parents with kids in elementary school feel confident in their kids arithmetic however you may only be sure of this, when calculations become second nature. Talking about column calculations this means that child knows how to add or subtract numbers regardless of amount of digits in them and is able to give answers spending no more than few seconds per column.
