How to calculate 87 multiplied by 43 using long multiplication. Here is step-by-step how to calculate 87 times 43 using long multiplication:

Step 1: Setup
Set up your multiplication problem like this:

              8 7
      x       4 3
                 

Step 2: Multiply
7 x 3 = 21. Put 1 below the line and 2 as a reminder on top:

              2  
              8 7
      x       4 3
                1

Step 3: Multiply
3 x 8 = 24. Take 24 and add 2 from the previous step to get 26. Enter 26 at the bottom:

              8 7
      x       4 3
            2 6 1

Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:

              8 7
      x       4 3
            2 6 1
      +         0

Step 5: Multiply
4 x 7 = 28. Put 8 below the line and 2 as a reminder on top:

              2  
              8 7
      x       4 3
            2 6 1
      +       8 0

Step 6: Multiply
4 x 8 = 32. Take 32 and add 2 from the previous step to get 34. Enter 34 at the bottom:

              8 7
      x       4 3
            2 6 1
      +   3 4 8 0

Step 7: Add to get answer
Add up the bottom two numbers (261 + 3480 = 3741) to get the answer:

              8 7
      x       4 3
            2 6 1
      +   3 4 8 0
      =   3 7 4 1

The bottom line is the answer. Therefore, 87 times 43 equals:

3741
