How to calculate 18 multiplied by 17

How to calculate 18 multiplied by 17 using long multiplication. Here is step-by-step how to calculate 18 times 17 using long multiplication:

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

	1	8
x	1	7

Step 2: Multiply
8 x 7 = 56. Put 6 below the line and 5 as a reminder on top:

	5
	1	8
x	1	7
		6

Step 3: Multiply
7 x 1 = 7. Take 7 and add 5 from the previous step to get 12. Enter 12 at the bottom:

		1	8
x		1	7
	1	2	6

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

		1	8
x		1	7
	1	2	6
+			0

Step 5: Multiply
1 x 8 = 8. Put 8 below the line and 0 as a reminder on top:

		0
		1	8
x		1	7
	1	2	6
+		8	0

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

		1	8
x		1	7
	1	2	6
+	1	8	0

Step 7: Add to get answer
Add up the bottom two numbers (126 + 180 = 306) to get the answer:

		1	8
x		1	7
	1	2	6
+	1	8	0
=	3	0	6

The bottom line is the answer. Therefore, 18 times 17 equals:

306
