when you multiply sum by a number like (7+9)plus 5 it is the same as multiplying each added by that factor (7time5)plus (9time5)
You can solve 8 × 45 using the distributive property by breaking down 45 into 40 + 5 and then multiplying 8 by both parts separately. After performing the calculations, you add the results to find that 8 × 45 = 360 . This method simplifies the multiplication process by using addition and smaller numbers.
