How to calculate 45 multiplied by 25

How to calculate 45 multiplied by 25 using long multiplication. Here is step-by-step how to calculate 45 times 25 using long multiplication:

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

	4	5
x	2	5

Step 2: Multiply
5 x 5 = 25. Put 5 below the line and 2 as a reminder on top:

	2
	4	5
x	2	5
		5

Step 3: Multiply
5 x 4 = 20. Take 20 and add 2 from the previous step to get 22. Enter 22 at the bottom:

		4	5
x		2	5
	2	2	5

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

		4	5
x		2	5
	2	2	5
+			0

Step 5: Multiply
2 x 5 = 10. Put 0 below the line and 1 as a reminder on top:

		1
		4	5
x		2	5
	2	2	5
+		0	0

Step 6: Multiply
2 x 4 = 8. Take 8 and add 1 from the previous step to get 9. Enter 9 at the bottom:

		4	5
x		2	5
	2	2	5
+	9	0	0

Step 7: Add to get answer
Add up the bottom two numbers (225 + 900 = 1125) to get the answer:

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

The bottom line is the answer. Therefore, 45 times 25 equals:

1125
