How to calculate 99 multiplied by 45 using long multiplication. Here is step-by-step how to calculate 99 times 45 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
9 | 9 | |||||||
x | 4 | 5 | ||||||
Step 2: Multiply
9 x 5 = 45. Put 5 below the line and 4 as a reminder on top:
4 | ||||||||
9 | 9 | |||||||
x | 4 | 5 | ||||||
5 |
Step 3: Multiply
5 x 9 = 45. Take 45 and add 4 from the previous step to get 49. Enter 49 at the bottom:
9 | 9 | |||||||
x | 4 | 5 | ||||||
4 | 9 | 5 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
9 | 9 | |||||||
x | 4 | 5 | ||||||
4 | 9 | 5 | ||||||
+ | 0 |
Step 5: Multiply
4 x 9 = 36. Put 6 below the line and 3 as a reminder on top:
3 | ||||||||
9 | 9 | |||||||
x | 4 | 5 | ||||||
4 | 9 | 5 | ||||||
+ | 6 | 0 |
Step 6: Multiply
4 x 9 = 36. Take 36 and add 3 from the previous step to get 39. Enter 39 at the bottom:
9 | 9 | |||||||
x | 4 | 5 | ||||||
4 | 9 | 5 | ||||||
+ | 3 | 9 | 6 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (495 + 3960 = 4455) to get the answer:
9 | 9 | |||||||
x | 4 | 5 | ||||||
4 | 9 | 5 | ||||||
+ | 3 | 9 | 6 | 0 | ||||
= | 4 | 4 | 5 | 5 |
The bottom line is the answer. Therefore, 99 times 45 equals:
