How to calculate 78 multiplied by 65

How to calculate 78 multiplied by 65 using long multiplication. Here is step-by-step how to calculate 78 times 65 using long multiplication:

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

	7	8
x	6	5

Step 2: Multiply
8 x 5 = 40. Put 0 below the line and 4 as a reminder on top:

	4
	7	8
x	6	5
		0

Step 3: Multiply
5 x 7 = 35. Take 35 and add 4 from the previous step to get 39. Enter 39 at the bottom:

		7	8
x		6	5
	3	9	0

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		6	5
	3	9	0
+			0

Step 5: Multiply
6 x 8 = 48. Put 8 below the line and 4 as a reminder on top:

		4
		7	8
x		6	5
	3	9	0

Step 6: Multiply
6 x 7 = 42. Take 42 and add 4 from the previous step to get 46. Enter 46 at the bottom:

			7	8
x			6	5
		3	9	0
+	4	6	8	0

Step 7: Add to get answer
Add up the bottom two numbers (390 + 4680 = 5070) to get the answer:

			7	8
x			6	5
		3	9	0
+	4	6	8	0
=	5	0	7	0

The bottom line is the answer. Therefore, 78 times 65 equals:

5070
