How to calculate 78 multiplied by 49

How to calculate 78 multiplied by 49 using long multiplication. Here is step-by-step how to calculate 78 times 49 using long multiplication:

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

	7	8
x	4	9

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

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

Step 5: Multiply
4 x 8 = 32. Put 2 below the line and 3 as a reminder on top:

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

Step 6: Multiply
4 x 7 = 28. Take 28 and add 3 from the previous step to get 31. Enter 31 at the bottom:

			7	8
x			4	9
		7	0	2
+	3	1	2	0

Step 7: Add to get answer
Add up the bottom two numbers (702 + 3120 = 3822) to get the answer:

			7	8
x			4	9
		7	0	2
+	3	1	2	0
=	3	8	2	2

The bottom line is the answer. Therefore, 78 times 49 equals:

3822
