How to calculate 86 multiplied by 77

How to calculate 86 multiplied by 77 using long multiplication. Here is step-by-step how to calculate 86 times 77 using long multiplication:

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

	8	6
x	7	7

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

	4
	8	6
x	7	7
		2

Step 3: Multiply
7 x 8 = 56. Take 56 and add 4 from the previous step to get 60. Enter 60 at the bottom:

		8	6
x		7	7
	6	0	2

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

		8	6
x		7	7
	6	0	2
+			0

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

		4
		8	6
x		7	7
	6	0	2

Step 6: Multiply
7 x 8 = 56. Take 56 and add 4 from the previous step to get 60. Enter 60 at the bottom:

			8	6
x			7	7
		6	0	2
+	6	0	2	0

Step 7: Add to get answer
Add up the bottom two numbers (602 + 6020 = 6622) to get the answer:

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

The bottom line is the answer. Therefore, 86 times 77 equals:
