How to calculate 70 multiplied by 39 using long multiplication. Here is step-by-step how to calculate 70 times 39 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
Step 2: Multiply
0 x 9 = 0. Put 0 below the line and 0 as a reminder on top:
| 0 | ||||||||
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
| 0 |
Step 3: Multiply
9 x 7 = 63. Take 63 and add 0 from the previous step to get 63. Enter 63 at the bottom:
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
| 6 | 3 | 0 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
| 6 | 3 | 0 | ||||||
| + | 0 |
Step 5: Multiply
3 x 0 = 0. Put 0 below the line and 0 as a reminder on top:
| 0 | ||||||||
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
| 6 | 3 | 0 | ||||||
| + | 0 | 0 |
Step 6: Multiply
3 x 7 = 21. Take 21 and add 0 from the previous step to get 21. Enter 21 at the bottom:
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
| 6 | 3 | 0 | ||||||
| + | 2 | 1 | 0 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (630 + 2100 = 2730) to get the answer:
| 7 | 0 | |||||||
| x | 3 | 9 | ||||||
| 6 | 3 | 0 | ||||||
| + | 2 | 1 | 0 | 0 | ||||
| = | 2 | 7 | 3 | 0 |
The bottom line is the answer. Therefore, 70 times 39 equals:
2730
