How to calculate 39 multiplied by 18

How to calculate 39 multiplied by 18 using long multiplication. Here is step-by-step how to calculate 39 times 18 using long multiplication:

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

	3	9
x	1	8

Step 2: Multiply
9 x 8 = 72. Put 2 below the line and 7 as a reminder on top:

	7
	3	9
x	1	8
		2

Step 3: Multiply
8 x 3 = 24. Take 24 and add 7 from the previous step to get 31. Enter 31 at the bottom:

		3	9
x		1	8
	3	1	2

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

		3	9
x		1	8
	3	1	2
+			0

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

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

Step 6: Multiply
1 x 3 = 3. Take 3 and add 0 from the previous step to get 3. Enter 3 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (312 + 390 = 702) to get the answer:

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

The bottom line is the answer. Therefore, 39 times 18 equals:

702
