How to calculate 91 multiplied by 15

How to calculate 91 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 91 times 15 using long multiplication:

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

	9	1
x	1	5

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

	0
	9	1
x	1	5
		5

Step 3: Multiply
5 x 9 = 45. Take 45 and add 0 from the previous step to get 45. Enter 45 at the bottom:

		9	1
x		1	5
	4	5	5

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

		9	1
x		1	5
	4	5	5
+			0

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

		0
		9	1
x		1	5
	4	5	5
+		1	0

Step 6: Multiply
1 x 9 = 9. Take 9 and add 0 from the previous step to get 9. Enter 9 at the bottom:

		9	1
x		1	5
	4	5	5
+	9	1	0

Step 7: Add to get answer
Add up the bottom two numbers (455 + 910 = 1365) to get the answer:

			9	1
x			1	5
		4	5	5
+		9	1	0
=	1	3	6	5

The bottom line is the answer. Therefore, 91 times 15 equals:

1365
