How to calculate 91 multiplied by 79 using long multiplication. Here is step-by-step how to calculate 91 times 79 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
Step 2: Multiply
1 x 9 = 9. Put 9 below the line and 0 as a reminder on top:
| 0 | ||||||||
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
| 9 |
Step 3: Multiply
9 x 9 = 81. Take 81 and add 0 from the previous step to get 81. Enter 81 at the bottom:
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
| 8 | 1 | 9 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
| 8 | 1 | 9 | ||||||
| + | 0 |
Step 5: Multiply
7 x 1 = 7. Put 7 below the line and 0 as a reminder on top:
| 0 | ||||||||
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
| 8 | 1 | 9 | ||||||
| + | 7 | 0 |
Step 6: Multiply
7 x 9 = 63. Take 63 and add 0 from the previous step to get 63. Enter 63 at the bottom:
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
| 8 | 1 | 9 | ||||||
| + | 6 | 3 | 7 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (819 + 6370 = 7189) to get the answer:
| 9 | 1 | |||||||
| x | 7 | 9 | ||||||
| 8 | 1 | 9 | ||||||
| + | 6 | 3 | 7 | 0 | ||||
| = | 7 | 1 | 8 | 9 |
The bottom line is the answer. Therefore, 91 times 79 equals:
7189
