How to calculate 72 multiplied by 18

How to calculate 72 multiplied by 18 using long multiplication. Here is step-by-step how to calculate 72 times 18 using long multiplication:

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

	7	2
x	1	8

Step 2: Multiply
2 x 8 = 16. Put 6 below the line and 1 as a reminder on top:

	1
	7	2
x	1	8
		6

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

		7	2
x		1	8
	5	7	6

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

		7	2
x		1	8
	5	7	6
+			0

Step 5: Multiply
1 x 2 = 2. Put 2 below the line and 0 as a reminder on top:

		0
		7	2
x		1	8
	5	7	6
+		2	0

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

		7	2
x		1	8
	5	7	6
+	7	2	0

Step 7: Add to get answer
Add up the bottom two numbers (576 + 720 = 1296) to get the answer:

			7	2
x			1	8
		5	7	6
+		7	2	0
=	1	2	9	6

The bottom line is the answer. Therefore, 72 times 18 equals:

1296
