How to calculate 87 multiplied by 85

How to calculate 87 multiplied by 85 using long multiplication. Here is step-by-step how to calculate 87 times 85 using long multiplication:

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

	8	7
x	8	5

Step 2: Multiply
7 x 5 = 35. Put 5 below the line and 3 as a reminder on top:

	3
	8	7
x	8	5
		5

Step 3: Multiply
5 x 8 = 40. Take 40 and add 3 from the previous step to get 43. Enter 43 at the bottom:

		8	7
x		8	5
	4	3	5

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	5
	4	3	5
+			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	5
	4	3	5
+		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	5
		4	3	5
+	6	9	6	0

Step 7: Add to get answer
Add up the bottom two numbers (435 + 6960 = 7395) to get the answer:

			8	7
x			8	5
		4	3	5
+	6	9	6	0
=	7	3	9	5

The bottom line is the answer. Therefore, 87 times 85 equals:

7395
