hmm... It's too simple example...
anyway:
3 × 5 = ( 2 + 1 ) × 5 = 2 × 5 + 1 × 5 = 10 + 5 = 15
3 X 5 = 3 X ( 2 + 3 ) = 6 + 9 *** = 15 Answer***
The break apart method involves breaking a number into smaller parts to simplify multiplication. For 3 × 5 , we break 3 into 2 + 1 , multiply each part by 5, and add the results to find 3 × 5 = 15 . This approach makes multiplication more manageable by using addition of simpler products.
