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
