How to calculate 54 multiplied by 54

How to calculate 54 multiplied by 54 using long multiplication. Here is step-by-step how to calculate 54 times 54 using long multiplication:

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

	5	4
x	5	4

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

	1
	5	4
x	5	4
		6

Step 3: Multiply
4 x 5 = 20. Take 20 and add 1 from the previous step to get 21. Enter 21 at the bottom:

		5	4
x		5	4
	2	1	6

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

		5	4
x		5	4
	2	1	6
+			0

Step 5: Multiply
5 x 4 = 20. Put 0 below the line and 2 as a reminder on top:

		2
		5	4
x		5	4
	2	1	6
+		0	0

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	4
x			5	4
		2	1	6
+	2	7	0	0

Step 7: Add to get answer
Add up the bottom two numbers (216 + 2700 = 2916) to get the answer:

			5	4
x			5	4
		2	1	6
+	2	7	0	0
=	2	9	1	6

The bottom line is the answer. Therefore, 54 times 54 equals:

2916
