How to calculate 78 multiplied by 39

How to calculate 78 multiplied by 39 using long multiplication. Here is step-by-step how to calculate 78 times 39 using long multiplication:

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

	7	8
x	3	9

Step 2: Multiply
8 x 9 = 72. Put 2 below the line and 7 as a reminder on top:

	7
	7	8
x	3	9
		2

Step 3: Multiply
9 x 7 = 63. Take 63 and add 7 from the previous step to get 70. Enter 70 at the bottom:

		7	8
x		3	9
	7	0	2

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		3	9
	7	0	2
+			0

Step 5: Multiply
3 x 8 = 24. Put 4 below the line and 2 as a reminder on top:

		2
		7	8
x		3	9
	7	0	2
+		4	0

Step 6: Multiply
3 x 7 = 21. Take 21 and add 2 from the previous step to get 23. Enter 23 at the bottom:

			7	8
x			3	9
		7	0	2
+	2	3	4	0

Step 7: Add to get answer
Add up the bottom two numbers (702 + 2340 = 3042) to get the answer:

			7	8
x			3	9
		7	0	2
+	2	3	4	0
=	3	0	4	2

The bottom line is the answer. Therefore, 78 times 39 equals:

3042
