How to calculate 85 multiplied by 39

How to calculate 85 multiplied by 39 using long multiplication. Here is step-by-step how to calculate 85 times 39 using long multiplication:

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

	8	5
x	3	9

Step 2: Multiply
5 x 9 = 45. Put 5 below the line and 4 as a reminder on top:

	4
	8	5
x	3	9
		5

Step 3: Multiply
9 x 8 = 72. Take 72 and add 4 from the previous step to get 76. Enter 76 at the bottom:

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

Step 5: Multiply
3 x 5 = 15. Put 5 below the line and 1 as a reminder on top:

		1
		8	5
x		3	9
	7	6	5
+		5	0

Step 6: Multiply
3 x 8 = 24. Take 24 and add 1 from the previous step to get 25. Enter 25 at the bottom:

			8	5
x			3	9
		7	6	5
+	2	5	5	0

Step 7: Add to get answer
Add up the bottom two numbers (765 + 2550 = 3315) to get the answer:

			8	5
x			3	9
		7	6	5
+	2	5	5	0
=	3	3	1	5

The bottom line is the answer. Therefore, 85 times 39 equals:

3315
