Question

use the standard algorithm to find the product of 435 and 783. record the products of each multiplying through each place value in 783. what is the product of multiplying by the ones digit is?

Answer 1

To find the product of 435 and 783 using the standard algorithm, we multiply each digit of 435 by each digit of 783 and then sum the results.

435
× 783
______________
2610 (435 × 3)
+ 2610 (435 × 8, shifted one place to the left)
+ 1740 (435 × 7, shifted two places to the left)
_______________
= 340305

Now let's focus on the multiplication of the ones digit:

435 × 3 = 1305

Therefore, the product of multiplying by the ones digit (3) is 1305.
