How to calculate 73 multiplied by 21

How to calculate 73 multiplied by 21 using long multiplication. Here is step-by-step how to calculate 73 times 21 using long multiplication:

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

	7	3
x	2	1

Step 2: Multiply
3 x 1 = 3. Put 3 below the line and 0 as a reminder on top:

	0
	7	3
x	2	1
		3

Step 3: Multiply
1 x 7 = 7. Take 7 and add 0 from the previous step to get 7. Enter 7 at the bottom:

	7	3
x	2	1
	7	3

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	2	1
	7	3
+		0

Step 5: Multiply
2 x 3 = 6. Put 6 below the line and 0 as a reminder on top:

	0
	7	3
x	2	1
	7	3
+	6	0

Step 6: Multiply
2 x 7 = 14. Take 14 and add 0 from the previous step to get 14. Enter 14 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (73 + 1460 = 1533) to get the answer:

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

The bottom line is the answer. Therefore, 73 times 21 equals:

1533
