How to calculate 99 multiplied by 39 using long multiplication. Here is step-by-step how to calculate 99 times 39 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
Step 2: Multiply
9 x 9 = 81. Put 1 below the line and 8 as a reminder on top:
| 8 | ||||||||
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
| 1 |
Step 3: Multiply
9 x 9 = 81. Take 81 and add 8 from the previous step to get 89. Enter 89 at the bottom:
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
| 8 | 9 | 1 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
| 8 | 9 | 1 | ||||||
| + | 0 |
Step 5: Multiply
3 x 9 = 27. Put 7 below the line and 2 as a reminder on top:
| 2 | ||||||||
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
| 8 | 9 | 1 | ||||||
| + | 7 | 0 |
Step 6: Multiply
3 x 9 = 27. Take 27 and add 2 from the previous step to get 29. Enter 29 at the bottom:
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
| 8 | 9 | 1 | ||||||
| + | 2 | 9 | 7 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (891 + 2970 = 3861) to get the answer:
| 9 | 9 | |||||||
| x | 3 | 9 | ||||||
| 8 | 9 | 1 | ||||||
| + | 2 | 9 | 7 | 0 | ||||
| = | 3 | 8 | 6 | 1 |
The bottom line is the answer. Therefore, 99 times 39 equals:
3861
