Find the value of 715×211 although these numbers aren't quite as nice as the ones from the example, the procedure is the same, so the difficulty is the same same excepting the ability to perform the calculation in your head. you may choose to use a calculator.

Who knows what procedure the question is referring to... You can take advantage of the distributive property of multiplication to compute the product:

715 * 211 = 715 * (200 + 10 + 1) = 715 * 200 + 715 * 10 + 715 * 1

Computing the remaining products is trivial.

715 * 200 = 2 * 715 * 100 = 1430 * 100 = 143,000

715 * 10 = 7150

715 * 1 = 715

Then

715 * 211 = 143,000 + 7150 + 715 = 150,865

-14 is the answer
