How to calculate 80 multiplied by 77

How to calculate 80 multiplied by 77 using long multiplication. Here is step-by-step how to calculate 80 times 77 using long multiplication:

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

	8	0
x	7	7

Step 2: Multiply
0 x 7 = 0. Put 0 below the line and 0 as a reminder on top:

	0
	8	0
x	7	7
		0

Step 3: Multiply
7 x 8 = 56. Take 56 and add 0 from the previous step to get 56. Enter 56 at the bottom:

		8	0
x		7	7
	5	6	0

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

		8	0
x		7	7
	5	6	0
+			0

Step 5: Multiply
7 x 0 = 0. Put 0 below the line and 0 as a reminder on top:

		0
		8	0
x		7	7
	5	6	0

Step 6: Multiply
7 x 8 = 56. Take 56 and add 0 from the previous step to get 56. Enter 56 at the bottom:

			8	0
x			7	7
		5	6	0
+	5	6	0	0

Step 7: Add to get answer
Add up the bottom two numbers (560 + 5600 = 6160) to get the answer:

			8	0
x			7	7
		5	6	0
+	5	6	0	0
=	6	1	6	0

The bottom line is the answer. Therefore, 80 times 77 equals:
