How to calculate 85 multiplied by 30 using long multiplication. Here is step-by-step how to calculate 85 times 30 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
8 | 5 | |||||||
x | 3 | 0 | ||||||
Step 2: Multiply
5 x 0 = 0. Put 0 below the line and 0 as a reminder on top:
0 | ||||||||
8 | 5 | |||||||
x | 3 | 0 | ||||||
0 |
Step 3: Multiply
0 x 8 = 0. Take 0 and add 0 from the previous step to get 0. Enter 0 at the bottom:
8 | 5 | |||||||
x | 3 | 0 | ||||||
0 | 0 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
8 | 5 | |||||||
x | 3 | 0 | ||||||
0 | 0 | |||||||
+ | 0 |
Step 5: Multiply
3 x 5 = 15. Put 5 below the line and 1 as a reminder on top:
1 | ||||||||
8 | 5 | |||||||
x | 3 | 0 | ||||||
0 | 0 | |||||||
+ | 5 | 0 |
Step 6: Multiply
3 x 8 = 24. Take 24 and add 1 from the previous step to get 25. Enter 25 at the bottom:
8 | 5 | |||||||
x | 3 | 0 | ||||||
0 | 0 | |||||||
+ | 2 | 5 | 5 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (0 + 2550 = 2550) to get the answer:
8 | 5 | |||||||
x | 3 | 0 | ||||||
0 | 0 | |||||||
+ | 2 | 5 | 5 | 0 | ||||
= | 2 | 5 | 5 | 0 |
The bottom line is the answer. Therefore, 85 times 30 equals:
2550
