How to calculate 77 multiplied by 23

How to calculate 77 multiplied by 23 using long multiplication. Here is step-by-step how to calculate 77 times 23 using long multiplication:

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

	7	7
x	2	3

Step 2: Multiply
7 x 3 = 21. Put 1 below the line and 2 as a reminder on top:

	2
	7	7
x	2	3
		1

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

		7	7
x		2	3
	2	3	1

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		2	3
	2	3	1
+			0

Step 5: Multiply
2 x 7 = 14. Put 4 below the line and 1 as a reminder on top:

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

Step 6: Multiply
2 x 7 = 14. Take 14 and add 1 from the previous step to get 15. Enter 15 at the bottom:

			7	7
x			2	3
		2	3	1
+	1	5	4	0

Step 7: Add to get answer
Add up the bottom two numbers (231 + 1540 = 1771) to get the answer:

			7	7
x			2	3
		2	3	1
+	1	5	4	0
=	1	7	7	1

The bottom line is the answer. Therefore, 77 times 23 equals:

1771
