How to calculate 99 multiplied by 13

How to calculate 99 multiplied by 13 using long multiplication. Here is step-by-step how to calculate 99 times 13 using long multiplication:

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

	9	9
x	1	3

Step 2: Multiply
9 x 3 = 27. Put 7 below the line and 2 as a reminder on top:

	2
	9	9
x	1	3
		7

Step 3: Multiply
3 x 9 = 27. Take 27 and add 2 from the previous step to get 29. Enter 29 at the bottom:

		9	9
x		1	3
	2	9	7

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

		9	9
x		1	3
	2	9	7
+			0

Step 5: Multiply
1 x 9 = 9. Put 9 below the line and 0 as a reminder on top:

		0
		9	9
x		1	3
	2	9	7
+		9	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	9
x		1	3
	2	9	7
+	9	9	0

Step 7: Add to get answer
Add up the bottom two numbers (297 + 990 = 1287) to get the answer:

			9	9
x			1	3
		2	9	7
+		9	9	0
=	1	2	8	7

The bottom line is the answer. Therefore, 99 times 13 equals:

1287
