How to calculate 86 multiplied by 81

How to calculate 86 multiplied by 81 using long multiplication. Here is step-by-step how to calculate 86 times 81 using long multiplication:

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

	8	6
x	8	1

Step 2: Multiply
6 x 1 = 6. Put 6 below the line and 0 as a reminder on top:

	0
	8	6
x	8	1
		6

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

	8	6
x	8	1
	8	6

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

	8	6
x	8	1
	8	6
+		0

Step 5: Multiply
8 x 6 = 48. Put 8 below the line and 4 as a reminder on top:

	4
	8	6
x	8	1
	8	6
+	8	0

Step 6: Multiply
8 x 8 = 64. Take 64 and add 4 from the previous step to get 68. Enter 68 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (86 + 6880 = 6966) to get the answer:

			8	6
x			8	1
			8	6
+	6	8	8	0
=	6	9	6	6

The bottom line is the answer. Therefore, 86 times 81 equals:

6966
