How to calculate 79 multiplied by 77 using long multiplication. Here is step-by-step how to calculate 79 times 77 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
Step 2: Multiply
9 x 7 = 63. Put 3 below the line and 6 as a reminder on top:
| 6 | ||||||||
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
| 3 |
Step 3: Multiply
7 x 7 = 49. Take 49 and add 6 from the previous step to get 55. Enter 55 at the bottom:
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
| 5 | 5 | 3 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
| 5 | 5 | 3 | ||||||
| + | 0 |
Step 5: Multiply
7 x 9 = 63. Put 3 below the line and 6 as a reminder on top:
| 6 | ||||||||
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
| 5 | 5 | 3 | ||||||
| + | 3 | 0 |
Step 6: Multiply
7 x 7 = 49. Take 49 and add 6 from the previous step to get 55. Enter 55 at the bottom:
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
| 5 | 5 | 3 | ||||||
| + | 5 | 5 | 3 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (553 + 5530 = 6083) to get the answer:
| 7 | 9 | |||||||
| x | 7 | 7 | ||||||
| 5 | 5 | 3 | ||||||
| + | 5 | 5 | 3 | 0 | ||||
| = | 6 | 0 | 8 | 3 |
The bottom line is the answer. Therefore, 79 times 77 equals:
6083
