How to calculate 83 multiplied by 78

How to calculate 83 multiplied by 78 using long multiplication. Here is step-by-step how to calculate 83 times 78 using long multiplication:

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

	8	3
x	7	8

Step 2: Multiply
3 x 8 = 24. Put 4 below the line and 2 as a reminder on top:

	2
	8	3
x	7	8
		4

Step 3: Multiply
8 x 8 = 64. Take 64 and add 2 from the previous step to get 66. Enter 66 at the bottom:

		8	3
x		7	8
	6	6	4

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

		8	3
x		7	8
	6	6	4
+			0

Step 5: Multiply
7 x 3 = 21. Put 1 below the line and 2 as a reminder on top:

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

Step 7: Add to get answer
Add up the bottom two numbers (664 + 5810 = 6474) to get the answer:

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

The bottom line is the answer. Therefore, 83 times 78 equals:

6474
