How to calculate 87 multiplied by 55

How to calculate 87 multiplied by 55 using long multiplication. Here is step-by-step how to calculate 87 times 55 using long multiplication:

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

	8	7
x	5	5

Step 2: Multiply
7 x 5 = 35. Put 5 below the line and 3 as a reminder on top:

	3
	8	7
x	5	5
		5

Step 3: Multiply
5 x 8 = 40. Take 40 and add 3 from the previous step to get 43. Enter 43 at the bottom:

		8	7
x		5	5
	4	3	5

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

		8	7
x		5	5
	4	3	5
+			0

Step 5: Multiply
5 x 7 = 35. Put 5 below the line and 3 as a reminder on top:

		3
		8	7
x		5	5
	4	3	5

Step 6: Multiply
5 x 8 = 40. Take 40 and add 3 from the previous step to get 43. Enter 43 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (435 + 4350 = 4785) to get the answer:

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

The bottom line is the answer. Therefore, 87 times 55 equals:

4785
