How to calculate 87 multiplied by 86

How to calculate 87 multiplied by 86 using long multiplication. Here is step-by-step how to calculate 87 times 86 using long multiplication:

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

	8	7
x	8	6

Step 2: Multiply
7 x 6 = 42. Put 2 below the line and 4 as a reminder on top:

	4
	8	7
x	8	6
		2

Step 3: Multiply
6 x 8 = 48. Take 48 and add 4 from the previous step to get 52. Enter 52 at the bottom:

		8	7
x		8	6
	5	2	2

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

		8	7
x		8	6
	5	2	2
+			0

Step 5: Multiply
8 x 7 = 56. Put 6 below the line and 5 as a reminder on top:

		5
		8	7
x		8	6
	5	2	2
+		6	0

Step 6: Multiply
8 x 8 = 64. Take 64 and add 5 from the previous step to get 69. Enter 69 at the bottom:

			8	7
x			8	6
		5	2	2
+	6	9	6	0

Step 7: Add to get answer
Add up the bottom two numbers (522 + 6960 = 7482) to get the answer:

			8	7
x			8	6
		5	2	2
+	6	9	6	0
=	7	4	8	2

The bottom line is the answer. Therefore, 87 times 86 equals:

7482
