How to calculate 72 multiplied by 15

How to calculate 72 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 72 times 15 using long multiplication:

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

	7	2
x	1	5

Step 2: Multiply
2 x 5 = 10. Put 0 below the line and 1 as a reminder on top:

	1
	7	2
x	1	5
		0

Step 3: Multiply
5 x 7 = 35. Take 35 and add 1 from the previous step to get 36. Enter 36 at the bottom:

		7	2
x		1	5
	3	6	0

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	5
	3	6	0
+			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	5
	3	6	0
+		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	5
	3	6	0
+	7	2	0

Step 7: Add to get answer
Add up the bottom two numbers (360 + 720 = 1080) to get the answer:

			7	2
x			1	5
		3	6	0
+		7	2	0
=	1	0	8	0

The bottom line is the answer. Therefore, 72 times 15 equals:

1080
