# Intro to standard way of multiplying multi-digit numbers

The standard algorithm for multiplying a multi-digit number by a single digit number involves multiplying each place value by the single digit, and regrouping as necessary. This method is equivalent to breaking the multi-digit number into parts, multiplying each part by the single digit, and adding the results together. Created by Sal Khan.

• Why this algorithm? My teacher tought me one other and this worked for me many times before.
• Unless your teacher requires you to use a certain algorithm, it is best to choose the algorithm you are most comfortable with. You may want to use two algorithms (or an algorithm and a shortcut trick) to check your answer.
