How to calculate 99 multiplied by 66

How to calculate 99 multiplied by 66 using long multiplication. Here is step-by-step how to calculate 99 times 66 using long multiplication:

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

	9	9
x	6	6

Step 2: Multiply
9 x 6 = 54. Put 4 below the line and 5 as a reminder on top:

	5
	9	9
x	6	6
		4

Step 3: Multiply
6 x 9 = 54. Take 54 and add 5 from the previous step to get 59. Enter 59 at the bottom:

		9	9
x		6	6
	5	9	4

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		6	6
	5	9	4
+			0

Step 5: Multiply
6 x 9 = 54. Put 4 below the line and 5 as a reminder on top:

+	5	9	4	0

Step 7: Add to get answer
Add up the bottom two numbers (594 + 5940 = 6534) to get the answer:

			9	9
x			6	6
		5	9	4
+	5	9	4	0
=	6	5	3	4

The bottom line is the answer. Therefore, 99 times 66 equals:
