How to calculate 81 multiplied by 52

How to calculate 81 multiplied by 52 using long multiplication. Here is step-by-step how to calculate 81 times 52 using long multiplication:

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

	8	1
x	5	2

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

	0
	8	1
x	5	2
		2

Step 3: 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		5	2
	1	6	2

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		5	2
	1	6	2
+			0

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

		0
		8	1
x		5	2
	1	6	2
+		5	0

Step 6: Multiply
5 x 8 = 40. Take 40 and add 0 from the previous step to get 40. Enter 40 at the bottom:

			8	1
x			5	2
		1	6	2
+	4	0	5	0

Step 7: Add to get answer
Add up the bottom two numbers (162 + 4050 = 4212) to get the answer:

			8	1
x			5	2
		1	6	2
+	4	0	5	0
=	4	2	1	2

The bottom line is the answer. Therefore, 81 times 52 equals:

4212
