How to calculate 87 multiplied by 80

How to calculate 87 multiplied by 80 using long multiplication. Here is step-by-step how to calculate 87 times 80 using long multiplication:

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

	8	7
x	8	0

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

	0
	8	7
x	8	0
		0

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

	8	7
x	8	0
	0	0

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

	8	7
x	8	0
	0	0
+		0

Step 5: Multiply
8 x 7 = 56. Put 6 below the line and 5 as a reminder on top:

	5
	8	7
x	8	0
	0	0
+	6	0

Step 6: Multiply
8 x 8 = 64. Take 64 and add 5 from the previous step to get 69. Enter 69 at the bottom:

			8	7
x			8	0
			0	0
+	6	9	6	0

Step 7: Add to get answer
Add up the bottom two numbers (0 + 6960 = 6960) to get the answer:

			8	7
x			8	0
			0	0
+	6	9	6	0
=	6	9	6	0

The bottom line is the answer. Therefore, 87 times 80 equals:

6960
