How to calculate 90 multiplied by 15

How to calculate 90 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 90 times 15 using long multiplication:

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

	9	0
x	1	5

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

	0
	9	0
x	1	5
		0

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	0
x		1	5
	4	5	0

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

		9	0
x		1	5
	4	5	0
+			0

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

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

Step 7: Add to get answer
Add up the bottom two numbers (450 + 900 = 1350) to get the answer:

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

The bottom line is the answer. Therefore, 90 times 15 equals:

1350
