How to calculate 49 multiplied by 45

How to calculate 49 multiplied by 45 using long multiplication. Here is step-by-step how to calculate 49 times 45 using long multiplication:

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

	4	9
x	4	5

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

	4
	4	9
x	4	5
		5

Step 3: Multiply
5 x 4 = 20. Take 20 and add 4 from the previous step to get 24. Enter 24 at the bottom:

		4	9
x		4	5
	2	4	5

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

		4	9
x		4	5
	2	4	5
+			0

Step 5: Multiply
4 x 9 = 36. Put 6 below the line and 3 as a reminder on top:

		3
		4	9
x		4	5
	2	4	5
+		6	0

Step 6: Multiply
4 x 4 = 16. Take 16 and add 3 from the previous step to get 19. Enter 19 at the bottom:

			4	9
x			4	5
		2	4	5
+	1	9	6	0

Step 7: Add to get answer
Add up the bottom two numbers (245 + 1960 = 2205) to get the answer:

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

The bottom line is the answer. Therefore, 49 times 45 equals:

2205
