How to calculate 78 multiplied by 47

How to calculate 78 multiplied by 47 using long multiplication. Here is step-by-step how to calculate 78 times 47 using long multiplication:

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

	7	8
x	4	7

Step 2: Multiply
8 x 7 = 56. Put 6 below the line and 5 as a reminder on top:

	5
	7	8
x	4	7
		6

Step 3: Multiply
7 x 7 = 49. Take 49 and add 5 from the previous step to get 54. Enter 54 at the bottom:

		7	8
x		4	7
	5	4	6

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

		7	8
x		4	7
	5	4	6
+			0

Step 5: Multiply
4 x 8 = 32. Put 2 below the line and 3 as a reminder on top:

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

Step 6: Multiply
4 x 7 = 28. Take 28 and add 3 from the previous step to get 31. Enter 31 at the bottom:

			7	8
x			4	7
		5	4	6
+	3	1	2	0

Step 7: Add to get answer
Add up the bottom two numbers (546 + 3120 = 3666) to get the answer:

			7	8
x			4	7
		5	4	6
+	3	1	2	0
=	3	6	6	6

The bottom line is the answer. Therefore, 78 times 47 equals:
