How to calculate 80 multiplied by 18

How to calculate 80 multiplied by 18 using long multiplication. Here is step-by-step how to calculate 80 times 18 using long multiplication:

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

	8	0
x	1	8

Step 2: Multiply
0 x 8 = 0. Put 0 below the line and 0 as a reminder on top:

	0
	8	0
x	1	8
		0

Step 3: Multiply
8 x 8 = 64. Take 64 and add 0 from the previous step to get 64. Enter 64 at the bottom:

		8	0
x		1	8
	6	4	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		1	8
	6	4	0
+			0

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

		0
		8	0
x		1	8
	6	4	0
+		0	0

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

		8	0
x		1	8
	6	4	0
+	8	0	0

Step 7: Add to get answer
Add up the bottom two numbers (640 + 800 = 1440) to get the answer:

			8	0
x			1	8
		6	4	0
+		8	0	0
=	1	4	4	0

The bottom line is the answer. Therefore, 80 times 18 equals:

1440
