How to calculate 84 multiplied by 84

How to calculate 84 multiplied by 84 using long multiplication. Here is step-by-step how to calculate 84 times 84 using long multiplication:

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

	8	4
x	8	4

Step 2: Multiply
4 x 4 = 16. Put 6 below the line and 1 as a reminder on top:

	1
	8	4
x	8	4
		6

Step 3: Multiply
4 x 8 = 32. Take 32 and add 1 from the previous step to get 33. Enter 33 at the bottom:

		8	4
x		8	4
	3	3	6

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

		8	4
x		8	4
	3	3	6
+			0

Step 5: Multiply
8 x 4 = 32. Put 2 below the line and 3 as a reminder on top:

Step 6: Multiply
8 x 8 = 64. Take 64 and add 3 from the previous step to get 67. Enter 67 at the bottom:

			8	4
x			8	4
		3	3	6
+	6	7	2	0

Step 7: Add to get answer
Add up the bottom two numbers (336 + 6720 = 7056) to get the answer:

			8	4
x			8	4
		3	3	6
+	6	7	2	0
=	7	0	5	6

The bottom line is the answer. Therefore, 84 times 84 equals:
