How to calculate 84 multiplied by 78

How to calculate 84 multiplied by 78 using long multiplication. Here is step-by-step how to calculate 84 times 78 using long multiplication:

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

	8	4
x	7	8

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

	3
	8	4
x	7	8
		2

Step 3: Multiply
8 x 8 = 64. Take 64 and add 3 from the previous step to get 67. Enter 67 at the bottom:

		8	4
x		7	8
	6	7	2

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

		8	4
x		7	8
	6	7	2
+			0

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

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

Step 6: Multiply
7 x 8 = 56. Take 56 and add 2 from the previous step to get 58. Enter 58 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (672 + 5880 = 6552) to get the answer:

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

The bottom line is the answer. Therefore, 84 times 78 equals:

6552
