How to calculate 99 multiplied by 28

How to calculate 99 multiplied by 28 using long multiplication. Here is step-by-step how to calculate 99 times 28 using long multiplication:

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

	9	9
x	2	8

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

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

Step 5: Multiply
2 x 9 = 18. Put 8 below the line and 1 as a reminder on top:

		1
		9	9
x		2	8
	7	9	2
+		8	0

Step 6: Multiply
2 x 9 = 18. Take 18 and add 1 from the previous step to get 19. Enter 19 at the bottom:

			9	9
x			2	8
		7	9	2
+	1	9	8	0

Step 7: Add to get answer
Add up the bottom two numbers (792 + 1980 = 2772) to get the answer:

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

The bottom line is the answer. Therefore, 99 times 28 equals:

2772
