How to calculate 77 multiplied by 66

How to calculate 77 multiplied by 66 using long multiplication. Here is step-by-step how to calculate 77 times 66 using long multiplication:

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

	7	7
x	6	6

Step 2: Multiply
7 x 6 = 42. Put 2 below the line and 4 as a reminder on top:

	4
	7	7
x	6	6
		2

Step 3: Multiply
6 x 7 = 42. Take 42 and add 4 from the previous step to get 46. Enter 46 at the bottom:

		7	7
x		6	6
	4	6	2

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

		7	7
x		6	6
	4	6	2
+			0

Step 5: Multiply
6 x 7 = 42. Put 2 below the line and 4 as a reminder on top:

		4
		7	7
x		6	6
	4	6	2
+		2	0

Step 6: Multiply
6 x 7 = 42. Take 42 and add 4 from the previous step to get 46. Enter 46 at the bottom:

			7	7
x			6	6
		4	6	2
+	4	6	2	0

Step 7: Add to get answer
Add up the bottom two numbers (462 + 4620 = 5082) to get the answer:

			7	7
x			6	6
		4	6	2
+	4	6	2	0
=	5	0	8	2

The bottom line is the answer. Therefore, 77 times 66 equals:

5082
