How to calculate 12 multiplied by 12

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

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

	1	2
x	1	2

Step 2: Multiply
2 x 2 = 4. Put 4 below the line and 0 as a reminder on top:

	0
	1	2
x	1	2
		4

Step 3: Multiply
2 x 1 = 2. Take 2 and add 0 from the previous step to get 2. Enter 2 at the bottom:

	1	2
x	1	2
	2	4

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

	1	2
x	1	2
	2	4
+		0

Step 5: Multiply
1 x 2 = 2. Put 2 below the line and 0 as a reminder on top:

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

Step 7: Add to get answer
Add up the bottom two numbers (24 + 120 = 144) to get the answer:

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

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

144
