How to calculate 42 multiplied by 25

How to calculate 42 multiplied by 25 using long multiplication. Here is step-by-step how to calculate 42 times 25 using long multiplication:

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

	4	2
x	2	5

Step 2: Multiply
2 x 5 = 10. Put 0 below the line and 1 as a reminder on top:

	1
	4	2
x	2	5
		0

Step 3: Multiply
5 x 4 = 20. Take 20 and add 1 from the previous step to get 21. Enter 21 at the bottom:

		4	2
x		2	5
	2	1	0

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

		4	2
x		2	5
	2	1	0
+			0

Step 5: Multiply
2 x 2 = 4. Put 4 below the line and 0 as a reminder on top:

		0
		4	2
x		2	5
	2	1	0
+		4	0

Step 6: Multiply
2 x 4 = 8. Take 8 and add 0 from the previous step to get 8. Enter 8 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (210 + 840 = 1050) to get the answer:

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

The bottom line is the answer. Therefore, 42 times 25 equals:

1050
