How to calculate 79 multiplied by 55 using long multiplication. Here is step-by-step how to calculate 79 times 55 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 7 | 9 | |||||||
| x | 5 | 5 | ||||||
Step 2: Multiply
9 x 5 = 45. Put 5 below the line and 4 as a reminder on top:
| 4 | ||||||||
| 7 | 9 | |||||||
| x | 5 | 5 | ||||||
| 5 |
Step 3: Multiply
5 x 7 = 35. Take 35 and add 4 from the previous step to get 39. Enter 39 at the bottom:
| 7 | 9 | |||||||
| x | 5 | 5 | ||||||
| 3 | 9 | 5 |
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 | 5 | 5 | ||||||
| 3 | 9 | 5 | ||||||
| + | 0 |
Step 5: Multiply
5 x 9 = 45. Put 5 below the line and 4 as a reminder on top:
| 4 | ||||||||
| 7 | 9 | |||||||
| x | 5 | 5 | ||||||
| 3 | 9 | 5 | ||||||
| + | 5 | 0 |
Step 6: Multiply
5 x 7 = 35. Take 35 and add 4 from the previous step to get 39. Enter 39 at the bottom:
| 7 | 9 | |||||||
| x | 5 | 5 | ||||||
| 3 | 9 | 5 | ||||||
| + | 3 | 9 | 5 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (395 + 3950 = 4345) to get the answer:
| 7 | 9 | |||||||
| x | 5 | 5 | ||||||
| 3 | 9 | 5 | ||||||
| + | 3 | 9 | 5 | 0 | ||||
| = | 4 | 3 | 4 | 5 |
The bottom line is the answer. Therefore, 79 times 55 equals:
