How to calculate 20 multiplied by 12

How to calculate 20 multiplied by 12 using long multiplication. Here is step-by-step how to calculate 20 times 12 using long multiplication:

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

	2	0
x	1	2

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

	0
	2	0
x	1	2
		0

Step 3: Multiply
2 x 2 = 4. Take 4 and add 0 from the previous step to get 4. Enter 4 at the bottom:

	2	0
x	1	2
	4	0

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

	2	0
x	1	2
	4	0
+		0

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

	0
	2	0
x	1	2
	4	0
+	0	0

Step 6: Multiply
1 x 2 = 2. Take 2 and add 0 from the previous step to get 2. Enter 2 at the bottom:

		2	0
x		1	2
		4	0
+	2	0	0

Step 7: Add to get answer
Add up the bottom two numbers (40 + 200 = 240) to get the answer:

		2	0
x		1	2
		4	0
+	2	0	0
=	2	4	0

The bottom line is the answer. Therefore, 20 times 12 equals:

240
