How to calculate 77 multiplied by 42

How to calculate 77 multiplied by 42 using long multiplication. Here is step-by-step how to calculate 77 times 42 using long multiplication:

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

	7	7
x	4	2

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

	1
	7	7
x	4	2
		4

Step 3: 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		4	2
	1	5	4

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		4	2
	1	5	4
+			0

Step 5: Multiply
4 x 7 = 28. Put 8 below the line and 2 as a reminder on top:

		2
		7	7
x		4	2
	1	5	4
+		8	0

Step 6: Multiply
4 x 7 = 28. Take 28 and add 2 from the previous step to get 30. Enter 30 at the bottom:

			7	7
x			4	2
		1	5	4
+	3	0	8	0

Step 7: Add to get answer
Add up the bottom two numbers (154 + 3080 = 3234) to get the answer:

			7	7
x			4	2
		1	5	4
+	3	0	8	0
=	3	2	3	4

The bottom line is the answer. Therefore, 77 times 42 equals:

3234
