How to calculate 81 multiplied by 24 using long multiplication. Here is step-by-step how to calculate 81 times 24 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
8 | 1 | |||||||
x | 2 | 4 | ||||||
Step 2: Multiply
1 x 4 = 4. Put 4 below the line and 0 as a reminder on top:
0 | ||||||||
8 | 1 | |||||||
x | 2 | 4 | ||||||
4 |
Step 3: Multiply
4 x 8 = 32. Take 32 and add 0 from the previous step to get 32. Enter 32 at the bottom:
8 | 1 | |||||||
x | 2 | 4 | ||||||
3 | 2 | 4 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
8 | 1 | |||||||
x | 2 | 4 | ||||||
3 | 2 | 4 | ||||||
+ | 0 |
Step 5: Multiply
2 x 1 = 2. Put 2 below the line and 0 as a reminder on top:
0 | ||||||||
8 | 1 | |||||||
x | 2 | 4 | ||||||
3 | 2 | 4 | ||||||
+ | 2 | 0 |
Step 6: Multiply
2 x 8 = 16. Take 16 and add 0 from the previous step to get 16. Enter 16 at the bottom:
8 | 1 | |||||||
x | 2 | 4 | ||||||
3 | 2 | 4 | ||||||
+ | 1 | 6 | 2 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (324 + 1620 = 1944) to get the answer:
8 | 1 | |||||||
x | 2 | 4 | ||||||
3 | 2 | 4 | ||||||
+ | 1 | 6 | 2 | 0 | ||||
= | 1 | 9 | 4 | 4 |
The bottom line is the answer. Therefore, 81 times 24 equals:
1944
