Front

What is addition with regrouping?

Back

Addition with regrouping is a method used when the sum of two or more digits in a column exceeds 10, requiring the 'carrying over' of the extra value to the next column.

Front

What is addition without regrouping?

Back

Addition without regrouping is when the sum of the digits in each column is less than 10, so no carrying over is needed.

Front

What is a key strategy for solving multi-step addition problems?

Back

A key strategy for solving multi-step addition problems is to break the problem down into smaller, manageable parts and solve each part step by step.

Front

What does it mean to 'carry over' in addition?

Back

'Carrying over' in addition means transferring a value from one column to the next when the sum exceeds 10.
