How to calculate 78 multiplied by 18

How to calculate 78 multiplied by 18 using long multiplication. Here is step-by-step how to calculate 78 times 18 using long multiplication:

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

	7	8
x	1	8

Step 2: Multiply
8 x 8 = 64. Put 4 below the line and 6 as a reminder on top:

	6
	7	8
x	1	8
		4

Step 3: Multiply
8 x 7 = 56. Take 56 and add 6 from the previous step to get 62. Enter 62 at the bottom:

		7	8
x		1	8
	6	2	4

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		1	8
	6	2	4
+			0

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

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

Step 6: Multiply
1 x 7 = 7. Take 7 and add 0 from the previous step to get 7. Enter 7 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (624 + 780 = 1404) to get the answer:

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

The bottom line is the answer. Therefore, 78 times 18 equals:

1404
