How to calculate 89 multiplied by 51

How to calculate 89 multiplied by 51 using long multiplication. Here is step-by-step how to calculate 89 times 51 using long multiplication:

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

	8	9
x	5	1

Step 2: Multiply
9 x 1 = 9. Put 9 below the line and 0 as a reminder on top:

	0
	8	9
x	5	1
		9

Step 3: Multiply
1 x 8 = 8. Take 8 and add 0 from the previous step to get 8. Enter 8 at the bottom:

	8	9
x	5	1
	8	9

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

	8	9
x	5	1
	8	9
+		0

Step 5: Multiply
5 x 9 = 45. Put 5 below the line and 4 as a reminder on top:

	4
	8	9
x	5	1
	8	9
+	5	0

Step 6: Multiply
5 x 8 = 40. Take 40 and add 4 from the previous step to get 44. Enter 44 at the bottom:

			8	9
x			5	1
			8	9
+	4	4	5	0

Step 7: Add to get answer
Add up the bottom two numbers (89 + 4450 = 4539) to get the answer:

			8	9
x			5	1
			8	9
+	4	4	5	0
=	4	5	3	9

The bottom line is the answer. Therefore, 89 times 51 equals:

4539
