How to calculate 82 multiplied by 15

How to calculate 82 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 82 times 15 using long multiplication:

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

	8	2
x	1	5

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

	1
	8	2
x	1	5
		0

Step 3: Multiply
5 x 8 = 40. Take 40 and add 1 from the previous step to get 41. Enter 41 at the bottom:

		8	2
x		1	5
	4	1	0

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

		8	2
x		1	5
	4	1	0
+			0

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

		0
		8	2
x		1	5
	4	1	0
+		2	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	2
x		1	5
	4	1	0
+	8	2	0

Step 7: Add to get answer
Add up the bottom two numbers (410 + 820 = 1230) to get the answer:

			8	2
x			1	5
		4	1	0
+		8	2	0
=	1	2	3	0

The bottom line is the answer. Therefore, 82 times 15 equals:

1230
