How to calculate 98 multiplied by 98

How to calculate 98 multiplied by 98 using long multiplication. Here is step-by-step how to calculate 98 times 98 using long multiplication:

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

	9	8
x	9	8

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

	6
	9	8
x	9	8
		4

Step 3: Multiply
8 x 9 = 72. Take 72 and add 6 from the previous step to get 78. Enter 78 at the bottom:

		9	8
x		9	8
	7	8	4

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

		9	8
x		9	8
	7	8	4
+			0

Step 5: Multiply
9 x 8 = 72. Put 2 below the line and 7 as a reminder on top:

		7
		9	8
x		9	8
	7	8	4
+		2	0

Step 6: Multiply
9 x 9 = 81. Take 81 and add 7 from the previous step to get 88. Enter 88 at the bottom:

			9	8
x			9	8
		7	8	4
+	8	8	2	0

Step 7: Add to get answer
Add up the bottom two numbers (784 + 8820 = 9604) to get the answer:

			9	8
x			9	8
		7	8	4
+	8	8	2	0
=	9	6	0	4

The bottom line is the answer. Therefore, 98 times 98 equals:

9604
