How to calculate 85 multiplied by 83

How to calculate 85 multiplied by 83 using long multiplication. Here is step-by-step how to calculate 85 times 83 using long multiplication:

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

	8	5
x	8	3

Step 2: Multiply
5 x 3 = 15. Put 5 below the line and 1 as a reminder on top:

	1
	8	5
x	8	3
		5

Step 3: 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		8	3
	2	5	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		8	3
	2	5	5
+			0

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

		4
		8	5
x		8	3
	2	5	5
+		0	0

Step 6: 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			8	3
		2	5	5
+	6	8	0	0

Step 7: Add to get answer
Add up the bottom two numbers (255 + 6800 = 7055) to get the answer:

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

The bottom line is the answer. Therefore, 85 times 83 equals:

7055
