How to calculate 85 multiplied by 78

How to calculate 85 multiplied by 78 using long multiplication. Here is step-by-step how to calculate 85 times 78 using long multiplication:

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

	8	5
x	7	8

Step 2: Multiply
5 x 8 = 40. Put 0 below the line and 4 as a reminder on top:

	4
	8	5
x	7	8
		0

Step 3: Multiply
8 x 8 = 64. Take 64 and add 4 from the previous step to get 68. Enter 68 at the bottom:

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

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

		3
		8	5
x		7	8
	6	8	0
+		5	0

Step 6: Multiply
7 x 8 = 56. Take 56 and add 3 from the previous step to get 59. Enter 59 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (680 + 5950 = 6630) to get the answer:

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

The bottom line is the answer. Therefore, 85 times 78 equals:
