How to calculate 81 multiplied by 48

How to calculate 81 multiplied by 48 using long multiplication. Here is step-by-step how to calculate 81 times 48 using long multiplication:

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

	8	1
x	4	8

Step 2: Multiply
1 x 8 = 8. Put 8 below the line and 0 as a reminder on top:

	0
	8	1
x	4	8
		8

Step 3: Multiply
8 x 8 = 64. Take 64 and add 0 from the previous step to get 64. Enter 64 at the bottom:

		8	1
x		4	8
	6	4	8

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		4	8
	6	4	8
+			0

Step 5: Multiply
4 x 1 = 4. Put 4 below the line and 0 as a reminder on top:

		0
		8	1
x		4	8
	6	4	8
+		4	0

Step 6: 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			4	8
		6	4	8
+	3	2	4	0

Step 7: Add to get answer
Add up the bottom two numbers (648 + 3240 = 3888) to get the answer:

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

The bottom line is the answer. Therefore, 81 times 48 equals:

3888
