Step 1: Setup
Set up your multiplication problem like this:
8 | 1 | |||||||
x | 6 | 9 | ||||||
Step 2: Multiply
1 x 9 = 9. Put 9 below the line and 0 as a reminder on top:
0 | ||||||||
8 | 1 | |||||||
x | 6 | 9 | ||||||
9 |
Step 3: Multiply
9 x 8 = 72. Take 72 and add 0 from the previous step to get 72. Enter 72 at the bottom:
8 | 1 | |||||||
x | 6 | 9 | ||||||
7 | 2 | 9 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
8 | 1 | |||||||
x | 6 | 9 | ||||||
7 | 2 | 9 | ||||||

8 | 1 | |||||||
x | 6 | 9 | ||||||
7 | 2 | 9 | ||||||
+ | 4 | 8 | 6 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (729 + 4860 = 5589) to get the answer:
8 | 1 | |||||||
x | 6 | 9 | ||||||
7 | 2 | 9 | ||||||
