How to calculate 98 multiplied by 78

How to calculate 98 multiplied by 78 using long multiplication. Here is step-by-step how to calculate 98 times 78 using long multiplication:

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

	9	8
x	7	8

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

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

Step 5: Multiply
7 x 8 = 56. Put 6 below the line and 5 as a reminder on top:

Step 6: Multiply
7 x 9 = 63. Take 63 and add 5 from the previous step to get 68. Enter 68 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (784 + 6860 = 7644) to get the answer:

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

The bottom line is the answer. Therefore, 98 times 78 equals:
