How to calculate 81 multiplied by 13

How to calculate 81 multiplied by 13 using long multiplication. Here is step-by-step how to calculate 81 times 13 using long multiplication:

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

	8	1
x	1	3

Step 2: Multiply
1 x 3 = 3. Put 3 below the line and 0 as a reminder on top:

	0
	8	1
x	1	3
		3

Step 3: Multiply
3 x 8 = 24. Take 24 and add 0 from the previous step to get 24. Enter 24 at the bottom:

		8	1
x		1	3
	2	4	3

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		1	3
	2	4	3
+			0

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

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

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

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

Step 7: Add to get answer
Add up the bottom two numbers (243 + 810 = 1053) to get the answer:

			8	1
x			1	3
		2	4	3
+		8	1	0
=	1	0	5	3

The bottom line is the answer. Therefore, 81 times 13 equals:

1053
