How to calculate 99 multiplied by 85

How to calculate 99 multiplied by 85 using long multiplication. Here is step-by-step how to calculate 99 times 85 using long multiplication:

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

	9	9
x	8	5

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

	4
	9	9
x	8	5
		5

Step 3: Multiply
5 x 9 = 45. Take 45 and add 4 from the previous step to get 49. Enter 49 at the bottom:

		9	9
x		8	5
	4	9	5

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

		9	9
x		8	5
	4	9	5
+			0

Step 5: Multiply
8 x 9 = 72. Put 2 below the line and 7 as a reminder on top:

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

Step 6: Multiply
8 x 9 = 72. Take 72 and add 7 from the previous step to get 79. Enter 79 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (495 + 7920 = 8415) to get the answer:

			9	9
x			8	5
		4	9	5
+	7	9	2	0
=	8	4	1	5

The bottom line is the answer. Therefore, 99 times 85 equals:

8415
