How to calculate 66 multiplied by 65

How to calculate 66 multiplied by 65 using long multiplication. Here is step-by-step how to calculate 66 times 65 using long multiplication:

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

	6	6
x	6	5

Step 2: Multiply
6 x 5 = 30. Put 0 below the line and 3 as a reminder on top:

	3
	6	6
x	6	5
		0

Step 3: Multiply
5 x 6 = 30. Take 30 and add 3 from the previous step to get 33. Enter 33 at the bottom:

		6	6
x		6	5
	3	3	0

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

		6	6
x		6	5
	3	3	0
+			0

Step 5: Multiply
6 x 6 = 36. Put 6 below the line and 3 as a reminder on top:

		3
		6	6
x		6	5
	3	3	0
+		6	0

Step 6: Multiply
6 x 6 = 36. Take 36 and add 3 from the previous step to get 39. Enter 39 at the bottom:

			6	6
x			6	5
		3	3	0
+	3	9	6	0

Step 7: Add to get answer
Add up the bottom two numbers (330 + 3960 = 4290) to get the answer:

			6	6
x			6	5
		3	3	0
+	3	9	6	0
=	4	2	9	0

The bottom line is the answer. Therefore, 66 times 65 equals:

4290
