How to calculate 54 multiplied by 42

How to calculate 54 multiplied by 42 using long multiplication. Here is step-by-step how to calculate 54 times 42 using long multiplication:

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

	5	4
x	4	2

Step 2: Multiply
4 x 2 = 8. Put 8 below the line and 0 as a reminder on top:

	0
	5	4
x	4	2
		8

Step 3: Multiply
2 x 5 = 10. Take 10 and add 0 from the previous step to get 10. Enter 10 at the bottom:

		5	4
x		4	2
	1	0	8

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

		5	4
x		4	2
	1	0	8
+			0

Step 5: Multiply
4 x 4 = 16. Put 6 below the line and 1 as a reminder on top:

		1
		5	4
x		4	2
	1	0	8
+		6	0

Step 6: Multiply
4 x 5 = 20. Take 20 and add 1 from the previous step to get 21. Enter 21 at the bottom:

			5	4
x			4	2
		1	0	8
+	2	1	6	0

Step 7: Add to get answer
Add up the bottom two numbers (108 + 2160 = 2268) to get the answer:

			5	4
x			4	2
		1	0	8
+	2	1	6	0
=	2	2	6	8

The bottom line is the answer. Therefore, 54 times 42 equals:

2268
