How to calculate 99 multiplied by 78

How to calculate 99 multiplied by 78 using long multiplication. Here is step-by-step how to calculate 99 times 78 using long multiplication:

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

	9	9
x	7	8

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

	7
	9	9
x	7	8
		2

Step 3: Multiply
8 x 9 = 72. Take 72 and add 7 from the previous step to get 79. Enter 79 at the bottom:

		9	9
x		7	8
	7	9	2

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

		9	9
x		7	8
	7	9	2
+			0

Step 5: Multiply
7 x 9 = 63. Put 3 below the line and 6 as a reminder on top:

		6
		9	9
x		7	8
	7	9	2
+		3	0

Step 6: Multiply
7 x 9 = 63. Take 63 and add 6 from the previous step to get 69. Enter 69 at the bottom:

			9	9
x			7	8
		7	9	2
+	6	9	3	0

Step 7: Add to get answer
Add up the bottom two numbers (792 + 6930 = 7722) to get the answer:

			9	9
x			7	8
		7	9	2
+	6	9	3	0
=	7	7	2	2

The bottom line is the answer. Therefore, 99 times 78 equals:

7722
