How to calculate 27 multiplied by 15

How to calculate 27 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 27 times 15 using long multiplication:

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

	2	7
x	1	5

Step 2: Multiply
7 x 5 = 35. Put 5 below the line and 3 as a reminder on top:

	3
	2	7
x	1	5
		5

Step 3: Multiply
5 x 2 = 10. Take 10 and add 3 from the previous step to get 13. Enter 13 at the bottom:

		2	7
x		1	5
	1	3	5

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

		2	7
x		1	5
	1	3	5
+			0

Step 5: Multiply
1 x 7 = 7. Put 7 below the line and 0 as a reminder on top:

		0
		2	7
x		1	5
	1	3	5
+		7	0

Step 6: Multiply
1 x 2 = 2. Take 2 and add 0 from the previous step to get 2. Enter 2 at the bottom:

		2	7
x		1	5
	1	3	5
+	2	7	0

Step 7: Add to get answer
Add up the bottom two numbers (135 + 270 = 405) to get the answer:

		2	7
x		1	5
	1	3	5
+	2	7	0
=	4	0	5

The bottom line is the answer. Therefore, 27 times 15 equals:

405
