How to calculate 69 multiplied by 69

How to calculate 69 multiplied by 69 using long multiplication. Here is step-by-step how to calculate 69 times 69 using long multiplication:

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

	6	9
x	6	9

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

	8
	6	9
x	6	9
		1

Step 3: Multiply
9 x 6 = 54. Take 54 and add 8 from the previous step to get 62. Enter 62 at the bottom:

		6	9
x		6	9
	6	2	1

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

		6	9
x		6	9
	6	2	1
+			0

Step 5: Multiply
6 x 9 = 54. Put 4 below the line and 5 as a reminder on top:

Step 6: Multiply
6 x 6 = 36. Take 36 and add 5 from the previous step to get 41. Enter 41 at the bottom:

			6	9
x			6	9
		6	2	1
+	4	1	4	0

Step 7: Add to get answer
Add up the bottom two numbers (621 + 4140 = 4761) to get the answer:

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

The bottom line is the answer. Therefore, 69 times 69 equals:
