How to calculate 55 multiplied by 15

How to calculate 55 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 55 times 15 using long multiplication:

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

	5	5
x	1	5

Step 2: Multiply
5 x 5 = 25. Put 5 below the line and 2 as a reminder on top:

	2
	5	5
x	1	5
		5

Step 3: Multiply
5 x 5 = 25. Take 25 and add 2 from the previous step to get 27. Enter 27 at the bottom:

		5	5
x		1	5
	2	7	5

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

		5	5
x		1	5
	2	7	5
+			0

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

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

Step 6: Multiply
1 x 5 = 5. Take 5 and add 0 from the previous step to get 5. Enter 5 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (275 + 550 = 825) to get the answer:

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

The bottom line is the answer. Therefore, 55 times 15 equals:

825
