How to calculate 77 multiplied by 51

How to calculate 77 multiplied by 51 using long multiplication. Here is step-by-step how to calculate 77 times 51 using long multiplication:

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

	7	7
x	5	1

Step 2: Multiply
7 x 1 = 7. Put 7 below the line and 0 as a reminder on top:

	0
	7	7
x	5	1
		7

Step 3: Multiply
1 x 7 = 7. Take 7 and add 0 from the previous step to get 7. Enter 7 at the bottom:

	7	7
x	5	1
	7	7

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

	7	7
x	5	1
	7	7
+		0

Step 5: Multiply
5 x 7 = 35. Put 5 below the line and 3 as a reminder on top:

	3
	7	7
x	5	1
	7	7
+	5	0

Step 6: Multiply
5 x 7 = 35. Take 35 and add 3 from the previous step to get 38. Enter 38 at the bottom:

			7	7
x			5	1
			7	7
+	3	8	5	0

Step 7: Add to get answer
Add up the bottom two numbers (77 + 3850 = 3927) to get the answer:

			7	7
x			5	1
			7	7
+	3	8	5	0
=	3	9	2	7

The bottom line is the answer. Therefore, 77 times 51 equals:

3927
