Ans. Breaking down complex operations into simpler ones can make calculations easier and reduce the chances of errors. For example, if you have to calculate 25 × 16, you can break it down as (20 × 10) + (20 × 6) + (5 × 10) + (5 × 6) = 200 + 120 + 50 + 30 = 400. By breaking it down, you can perform each operation separately and then add the results together.
