How to calculate 85 multiplied by 66

How to calculate 85 multiplied by 66 using long multiplication. Here is step-by-step how to calculate 85 times 66 using long multiplication:

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

	8	5
x	6	6

Step 2: Multiply
5 x 6 = 30. Put 0 below the line and 3 as a reminder on top:

	3
	8	5
x	6	6
		0

Step 3: Multiply
6 x 8 = 48. Take 48 and add 3 from the previous step to get 51. Enter 51 at the bottom:

		8	5
x		6	6
	5	1	0

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

		8	5
x		6	6
	5	1	0
+			0

Step 5: Multiply
6 x 5 = 30. Put 0 below the line and 3 as a reminder on top:

		3
		8	5
x		6	6
	5	1	0

Step 6: Multiply
6 x 8 = 48. Take 48 and add 3 from the previous step to get 51. Enter 51 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (510 + 5100 = 5610) to get the answer:

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

The bottom line is the answer. Therefore, 85 times 66 equals:
