How to calculate 99 multiplied by 25

How to calculate 99 multiplied by 25 using long multiplication. Here is step-by-step how to calculate 99 times 25 using long multiplication:

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

	9	9
x	2	5

Step 2: Multiply
9 x 5 = 45. Put 5 below the line and 4 as a reminder on top:

	4
	9	9
x	2	5
		5

Step 3: Multiply
5 x 9 = 45. Take 45 and add 4 from the previous step to get 49. Enter 49 at the bottom:

		9	9
x		2	5
	4	9	5

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	5
	4	9	5
+			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	5
	4	9	5
+		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	5
		4	9	5
+	1	9	8	0

Step 7: Add to get answer
Add up the bottom two numbers (495 + 1980 = 2475) to get the answer:

			9	9
x			2	5
		4	9	5
+	1	9	8	0
=	2	4	7	5

The bottom line is the answer. Therefore, 99 times 25 equals:

2475
