How to calculate 73 multiplied by 45

How to calculate 73 multiplied by 45 using long multiplication. Here is step-by-step how to calculate 73 times 45 using long multiplication:

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

	7	3
x	4	5

Step 2: Multiply
3 x 5 = 15. Put 5 below the line and 1 as a reminder on top:

	1
	7	3
x	4	5
		5

Step 3: Multiply
5 x 7 = 35. Take 35 and add 1 from the previous step to get 36. Enter 36 at the bottom:

		7	3
x		4	5
	3	6	5

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

		7	3
x		4	5
	3	6	5
+			0

Step 5: Multiply
4 x 3 = 12. Put 2 below the line and 1 as a reminder on top:

		1
		7	3
x		4	5
	3	6	5
+		2	0

Step 6: Multiply
4 x 7 = 28. Take 28 and add 1 from the previous step to get 29. Enter 29 at the bottom:

			7	3
x			4	5
		3	6	5
+	2	9	2	0

Step 7: Add to get answer
Add up the bottom two numbers (365 + 2920 = 3285) to get the answer:

			7	3
x			4	5
		3	6	5
+	2	9	2	0
=	3	2	8	5

The bottom line is the answer. Therefore, 73 times 45 equals:

3285
