How to calculate 85 multiplied by 54

How to calculate 85 multiplied by 54 using long multiplication. Here is step-by-step how to calculate 85 times 54 using long multiplication:

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

	8	5
x	5	4

Step 2: Multiply
5 x 4 = 20. Put 0 below the line and 2 as a reminder on top:

	2
	8	5
x	5	4
		0

Step 3: Multiply
4 x 8 = 32. Take 32 and add 2 from the previous step to get 34. Enter 34 at the bottom:

		8	5
x		5	4
	3	4	0

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

		8	5
x		5	4
	3	4	0
+			0

Step 5: Multiply
5 x 5 = 25. Put 5 below the line and 2 as a reminder on top:

Step 6: Multiply
5 x 8 = 40. Take 40 and add 2 from the previous step to get 42. Enter 42 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (340 + 4250 = 4590) to get the answer:

			8	5
x			5	4
		3	4	0
+	4	2	5	0
=	4	5	9	0

The bottom line is the answer. Therefore, 85 times 54 equals:
