How to calculate 39 multiplied by 12

How to calculate 39 multiplied by 12 using long multiplication. Here is step-by-step how to calculate 39 times 12 using long multiplication:

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

	3	9
x	1	2

Step 2: Multiply
9 x 2 = 18. Put 8 below the line and 1 as a reminder on top:

	1
	3	9
x	1	2
		8

Step 3: Multiply
2 x 3 = 6. Take 6 and add 1 from the previous step to get 7. Enter 7 at the bottom:

	3	9
x	1	2
	7	8

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	2
	7	8
+		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	2
	7	8
+	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	2
		7	8
+	3	9	0

Step 7: Add to get answer
Add up the bottom two numbers (78 + 390 = 468) to get the answer:

		3	9
x		1	2
		7	8
+	3	9	0
=	4	6	8

The bottom line is the answer. Therefore, 39 times 12 equals:

468
