How to calculate 82 multiplied by 77

How to calculate 82 multiplied by 77 using long multiplication. Here is step-by-step how to calculate 82 times 77 using long multiplication:

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

	8	2
x	7	7

Step 2: Multiply
2 x 7 = 14. Put 4 below the line and 1 as a reminder on top:

	1
	8	2
x	7	7
		4

Step 3: Multiply
7 x 8 = 56. Take 56 and add 1 from the previous step to get 57. Enter 57 at the bottom:

		8	2
x		7	7
	5	7	4

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

		8	2
x		7	7
	5	7	4
+			0

Step 5: Multiply
7 x 2 = 14. Put 4 below the line and 1 as a reminder on top:

Step 6: Multiply
7 x 8 = 56. Take 56 and add 1 from the previous step to get 57. Enter 57 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (574 + 5740 = 6314) to get the answer:

			8	2
x			7	7
		5	7	4
+	5	7	4	0
=	6	3	1	4

The bottom line is the answer. Therefore, 82 times 77 equals:
