How to calculate 69 multiplied by 21 using long multiplication. Here is step-by-step how to calculate 69 times 21 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
6 | 9 | |||||||
x | 2 | 1 | ||||||
Step 2: Multiply
9 x 1 = 9. Put 9 below the line and 0 as a reminder on top:
0 | ||||||||
6 | 9 | |||||||
x | 2 | 1 | ||||||
9 |
Step 3: Multiply
1 x 6 = 6. Take 6 and add 0 from the previous step to get 6. Enter 6 at the bottom:
6 | 9 | |||||||
x | 2 | 1 | ||||||
6 | 9 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
6 | 9 | |||||||
x | 2 | 1 | ||||||
6 | 9 | |||||||
+ | 0 |
Step 5: Multiply
2 x 9 = 18. Put 8 below the line and 1 as a reminder on top:
1 | ||||||||
6 | 9 | |||||||
x | 2 | 1 | ||||||
6 | 9 | |||||||
+ | 8 | 0 |
Step 6: Multiply
2 x 6 = 12. Take 12 and add 1 from the previous step to get 13. Enter 13 at the bottom:
6 | 9 | |||||||
x | 2 | 1 | ||||||
6 | 9 | |||||||
+ | 1 | 3 | 8 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (69 + 1380 = 1449) to get the answer:
6 | 9 | |||||||
x | 2 | 1 | ||||||
6 | 9 | |||||||
+ | 1 | 3 | 8 | 0 | ||||
= | 1 | 4 | 4 | 9 |
The bottom line is the answer. Therefore, 69 times 21 equals:
