How to calculate 47 multiplied by 21

How to calculate 47 multiplied by 21 using long multiplication. Here is step-by-step how to calculate 47 times 21 using long multiplication:

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

	4	7
x	2	1

Step 2: Multiply
7 x 1 = 7. Put 7 below the line and 0 as a reminder on top:

	0
	4	7
x	2	1
		7

Step 3: Multiply
1 x 4 = 4. Take 4 and add 0 from the previous step to get 4. Enter 4 at the bottom:

	4	7
x	2	1
	4	7

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

	4	7
x	2	1
	4	7
+		0

Step 5: Multiply
2 x 7 = 14. Put 4 below the line and 1 as a reminder on top:

	1
	4	7
x	2	1
	4	7
+	4	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	7
x		2	1
		4	7
+	9	4	0

Step 7: Add to get answer
Add up the bottom two numbers (47 + 940 = 987) to get the answer:

		4	7
x		2	1
		4	7
+	9	4	0
=	9	8	7

The bottom line is the answer. Therefore, 47 times 21 equals:

987
