How to calculate 99 multiplied by 79

How to calculate 99 multiplied by 79 using long multiplication. Here is step-by-step how to calculate 99 times 79 using long multiplication:

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

	9	9
x	7	9

Step 2: Multiply
9 x 9 = 81. Put 1 below the line and 8 as a reminder on top:

	8
	9	9
x	7	9
		1

Step 3: Multiply
9 x 9 = 81. Take 81 and add 8 from the previous step to get 89. Enter 89 at the bottom:

		9	9
x		7	9
	8	9	1

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	9
	8	9	1
+			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	9
	8	9	1
+		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	9
		8	9	1
+	6	9	3	0

Step 7: Add to get answer
Add up the bottom two numbers (891 + 6930 = 7821) to get the answer:

			9	9
x			7	9
		8	9	1
+	6	9	3	0
=	7	8	2	1

The bottom line is the answer. Therefore, 99 times 79 equals:

7821
