How to calculate 85 multiplied by 57

How to calculate 85 multiplied by 57 using long multiplication. Here is step-by-step how to calculate 85 times 57 using long multiplication:

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

	8	5
x	5	7

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

	3
	8	5
x	5	7
		5

Step 3: 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		5	7
	5	9	5

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		5	7
	5	9	5
+			0

Step 5: Multiply
5 x 5 = 25. Put 5 below the line and 2 as a reminder on top:

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

Step 6: Multiply
5 x 8 = 40. Take 40 and add 2 from the previous step to get 42. Enter 42 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (595 + 4250 = 4845) to get the answer:

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

The bottom line is the answer. Therefore, 85 times 57 equals:
