How to calculate 45 multiplied by 12 using long multiplication. Here is step-by-step how to calculate 45 times 12 using long multiplication:

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

	4	5
x	1	2

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

	1
	4	5
x	1	2
		0

Step 3: Multiply
2 x 4 = 8. Take 8 and add 1 from the previous step to get 9. Enter 9 at the bottom:

	4	5
x	1	2
	9	0

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

	4	5
x	1	2
	9	0
+		0

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

	0
	4	5
x	1	2

1 x 4 = 4. Take 4 and add 0 from the previous step to get 4. Enter 4 at the bottom:

		4	5
x		1	2
		9	0
+	4	5	0

Step 7: Add to get answer
Add up the bottom two numbers (90 + 450 = 540) to get the answer:

		4	5
x		1	2
		9	0
+	4	5	0
=	5	4	0

The bottom line is the answer. Therefore, 45 times 12 equals:

540
