How to calculate 68 multiplied by 68

How to calculate 68 multiplied by 68 using long multiplication. Here is step-by-step how to calculate 68 times 68 using long multiplication:

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

	6	8
x	6	8

Step 2: Multiply
8 x 8 = 64. Put 4 below the line and 6 as a reminder on top:

	6
	6	8
x	6	8
		4

Step 3: Multiply
8 x 6 = 48. Take 48 and add 6 from the previous step to get 54. Enter 54 at the bottom:

		6	8
x		6	8
	5	4	4

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

		6	8
x		6	8
	5	4	4
+			0

Step 5: Multiply
6 x 8 = 48. Put 8 below the line and 4 as a reminder on top:

		4
		6	8
x		6	8
	5	4	4
+		8	0

Step 6: Multiply
6 x 6 = 36. Take 36 and add 4 from the previous step to get 40. Enter 40 at the bottom:

			6	8
x			6	8
		5	4	4
+	4	0	8	0

Step 7: Add to get answer
Add up the bottom two numbers (544 + 4080 = 4624) to get the answer:

			6	8
x			6	8
		5	4	4
+	4	0	8	0
=	4	6	2	4

The bottom line is the answer. Therefore, 68 times 68 equals:

4624
