Question

how do you do expanded algorithm? here's an example to use for the answer 58*26

Answer 1

Instead of multiplying a single digit at a time with a number of digits, single digit products are written down and eventually added.

58*26 would be calculated as
8*6=48
8*20=160
50*6=300
50*20=1000
then add up the four numbers to get 1508.

You can take a look at the site:

The formatting limitations of this site does not allow me to align vertical columns, so it will not be illustrative.

Answer 2

Thank you so much!! I understand expanded algorithm so much better now!
