How to calculate 89 multiplied by 85 using long multiplication. Here is step-by-step how to calculate 89 times 85 using long multiplication:
Step 1: Setup
Set up your multiplication problem like this:
8 | 9 | |||||||
x | 8 | 5 | ||||||
Step 2: Multiply
9 x 5 = 45. Put 5 below the line and 4 as a reminder on top:
4 | ||||||||
8 | 9 | |||||||
x | 8 | 5 | ||||||
5 |
Step 3: Multiply
5 x 8 = 40. Take 40 and add 4 from the previous step to get 44. Enter 44 at the bottom:
8 | 9 | |||||||
x | 8 | 5 | ||||||
4 | 4 | 5 |
Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
8 | 9 | |||||||
x | 8 | 5 | ||||||
4 | 4 | 5 | ||||||
+ | 0 |
Step 5: Multiply
8 x 9 = 72. Put 2 below the line and 7 as a reminder on top:
7 | ||||||||
8 | 9 | |||||||
x | 8 | 5 | ||||||
4 | 4 | 5 | ||||||
+ | 2 | 0 |
Step 6: Multiply
8 x 8 = 64. Take 64 and add 7 from the previous step to get 71. Enter 71 at the bottom:
8 | 9 | |||||||
x | 8 | 5 | ||||||
4 | 4 | 5 | ||||||
+ | 7 | 1 | 2 | 0 |
Step 7: Add to get answer
Add up the bottom two numbers (445 + 7120 = 7565) to get the answer:
8 | 9 | |||||||
x | 8 | 5 | ||||||
4 | 4 | 5 | ||||||
+ | 7 | 1 | 2 | 0 | ||||
= | 7 | 5 | 6 | 5 |
The bottom line is the answer. Therefore, 89 times 85 equals:
7565
