How to calculate 78 multiplied by 54 using long multiplication. Here is step-by-step how to calculate 78 times 54 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
7 | 8 | |||||||
x | 5 | 4 | ||||||
Step 2: Multiply
8 x 4 = 32. Put 2 below the line and 3 as a reminder on top:
3 | ||||||||
7 | 8 | |||||||
x | 5 | 4 | ||||||
2 |
Step 3: Multiply
4 x 7 = 28. Take 28 and add 3 from the previous step to get 31. Enter 31 at the bottom:
7 | 8 | |||||||
x | 5 | 4 | ||||||
3 | 1 | 2 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
7 | 8 | |||||||
x | 5 | 4 | ||||||
3 | 1 | 2 | ||||||
+ | 0 |
Step 5: Multiply
5 x 8 = 40. Put 0 below the line and 4 as a reminder on top:
4 | ||||||||
7 | 8 | |||||||
x | 5 | 4 | ||||||
3 | 1 | 2 | ||||||
+ | 0 | 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 | 8 | |||||||
x | 5 | 4 | ||||||
3 | 1 | 2 | ||||||
+ | 3 | 9 | 0 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (312 + 3900 = 4212) to get the answer:
7 | 8 | |||||||
x | 5 | 4 | ||||||
3 | 1 | 2 | ||||||
+ | 3 | 9 | 0 | 0 | ||||
= | 4 | 2 | 1 | 2 |
The bottom line is the answer. Therefore, 78 times 54 equals:
4212
