How to calculate 45 multiplied by 28

How to calculate 45 multiplied by 28 using long multiplication. Here is step-by-step how to calculate 45 times 28 using long multiplication:

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

	4	5
x	2	8

Step 2: Multiply
5 x 8 = 40. Put 0 below the line and 4 as a reminder on top:

	4
	4	5
x	2	8
		0

Step 3: Multiply
8 x 4 = 32. Take 32 and add 4 from the previous step to get 36. Enter 36 at the bottom:

		4	5
x		2	8
	3	6	0

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

Step 7: Add to get answer
Add up the bottom two numbers (360 + 900 = 1260) to get the answer:

			4	5
x			2	8
		3	6	0
+		9	0	0
=	1	2	6	0

The bottom line is the answer. Therefore, 45 times 28 equals:

1260
