How to calculate 47 multiplied by 42

How to calculate 47 multiplied by 42 using long multiplication. Here is step-by-step how to calculate 47 times 42 using long multiplication:

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

	4	7
x	4	2

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

	1
	4	7
x	4	2
		4

Step 3: 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	4	2
	9	4

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	4	2
	9	4
+		0

Step 5: Multiply
4 x 7 = 28. Put 8 below the line and 2 as a reminder on top:

	2
	4	7
x	4	2
	9	4
+	8	0

Step 6: Multiply
4 x 4 = 16. Take 16 and add 2 from the previous step to get 18. Enter 18 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (94 + 1880 = 1974) to get the answer:

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

The bottom line is the answer. Therefore, 47 times 42 equals:

1974
