How to calculate 28 multiplied by 28

How to calculate 28 multiplied by 28 using long multiplication. Here is step-by-step how to calculate 28 times 28 using long multiplication:

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

	2	8
x	2	8

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

	6
	2	8
x	2	8
		4

Step 3: Multiply
8 x 2 = 16. Take 16 and add 6 from the previous step to get 22. Enter 22 at the bottom:

		2	8
x		2	8
	2	2	4

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

		2	8
x		2	8
	2	2	4
+			0

Step 5: Multiply
2 x 8 = 16. Put 6 below the line and 1 as a reminder on top:

		1
		2	8
x		2	8
	2	2	4
+		6	0

Step 6: Multiply
2 x 2 = 4. Take 4 and add 1 from the previous step to get 5. Enter 5 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (224 + 560 = 784) to get the answer:

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

The bottom line is the answer. Therefore, 28 times 28 equals:

784
