How to calculate 55 multiplied by 55

How to calculate 55 multiplied by 55 using long multiplication. Here is step-by-step how to calculate 55 times 55 using long multiplication:

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

	5	5
x	5	5

Step 2: Multiply
5 x 5 = 25. Put 5 below the line and 2 as a reminder on top:

	2
	5	5
x	5	5
		5

Step 3: Multiply
5 x 5 = 25. Take 25 and add 2 from the previous step to get 27. Enter 27 at the bottom:

		5	5
x		5	5
	2	7	5

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

		5	5
x		5	5
	2	7	5
+			0

Step 5: Multiply
5 x 5 = 25. Put 5 below the line and 2 as a reminder on top:

Step 6: Multiply
5 x 5 = 25. Take 25 and add 2 from the previous step to get 27. Enter 27 at the bottom:

			5	5
x			5	5
		2	7	5
+	2	7	5	0

Step 7: Add to get answer
Add up the bottom two numbers (275 + 2750 = 3025) to get the answer:

			5	5
x			5	5
		2	7	5
+	2	7	5	0
=	3	0	2	5

The bottom line is the answer. Therefore, 55 times 55 equals:
