How to calculate 19 multiplied by 19

How to calculate 19 multiplied by 19 using long multiplication. Here is step-by-step how to calculate 19 times 19 using long multiplication:

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

	1	9
x	1	9

Step 2: Multiply
9 x 9 = 81. Put 1 below the line and 8 as a reminder on top:

	8
	1	9
x	1	9
		1

Step 3: Multiply
9 x 1 = 9. Take 9 and add 8 from the previous step to get 17. Enter 17 at the bottom:

		1	9
x		1	9
	1	7	1

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

		1	9
x		1	9
	1	7	1
+			0

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

		0
		1	9
x		1	9
	1	7	1
+		9	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	9
x		1	9
	1	7	1
+	1	9	0

Step 7: Add to get answer
Add up the bottom two numbers (171 + 190 = 361) to get the answer:

		1	9
x		1	9
	1	7	1
+	1	9	0
=	3	6	1

The bottom line is the answer. Therefore, 19 times 19 equals:

361
