How to calculate 84 multiplied by 79 using long multiplication. Here is step-by-step how to calculate 84 times 79 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
Step 2: Multiply
4 x 9 = 36. Put 6 below the line and 3 as a reminder on top:
| 3 | ||||||||
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
| 6 |
Step 3: Multiply
9 x 8 = 72. Take 72 and add 3 from the previous step to get 75. Enter 75 at the bottom:
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
| 7 | 5 | 6 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
| 7 | 5 | 6 | ||||||
| + | 0 |
Step 5: Multiply
7 x 4 = 28. Put 8 below the line and 2 as a reminder on top:
| 2 | ||||||||
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
| 7 | 5 | 6 | ||||||
| + | 8 | 0 |
Step 6: Multiply
7 x 8 = 56. Take 56 and add 2 from the previous step to get 58. Enter 58 at the bottom:
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
| 7 | 5 | 6 | ||||||
| + | 5 | 8 | 8 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (756 + 5880 = 6636) to get the answer:
| 8 | 4 | |||||||
| x | 7 | 9 | ||||||
| 7 | 5 | 6 | ||||||
| + | 5 | 8 | 8 | 0 | ||||
| = | 6 | 6 | 3 | 6 |
The bottom line is the answer. Therefore, 84 times 79 equals:
6636
