How to calculate 45 multiplied by 19 using long multiplication. Here is step-by-step how to calculate 45 times 19 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
Step 2: Multiply
5 x 9 = 45. Put 5 below the line and 4 as a reminder on top:
| 4 | ||||||||
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
| 5 |
Step 3: Multiply
9 x 4 = 36. Take 36 and add 4 from the previous step to get 40. Enter 40 at the bottom:
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
| 4 | 0 | 5 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
| 4 | 0 | 5 | ||||||
| + | 0 |
Step 5: Multiply
1 x 5 = 5. Put 5 below the line and 0 as a reminder on top:
| 0 | ||||||||
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
| 4 | 0 | 5 | ||||||
| + | 5 | 0 |
Step 6: Multiply
1 x 4 = 4. Take 4 and add 0 from the previous step to get 4. Enter 4 at the bottom:
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
| 4 | 0 | 5 | ||||||
| + | 4 | 5 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (405 + 450 = 855) to get the answer:
| 4 | 5 | |||||||
| x | 1 | 9 | ||||||
| 4 | 0 | 5 | ||||||
| + | 4 | 5 | 0 | |||||
| = | 8 | 5 | 5 |
The bottom line is the answer. Therefore, 45 times 19 equals:
855
