How to calculate 89 multiplied by 72

How to calculate 89 multiplied by 72 using long multiplication. Here is step-by-step how to calculate 89 times 72 using long multiplication:

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

	8	9
x	7	2

Step 2: Multiply
9 x 2 = 18. Put 8 below the line and 1 as a reminder on top:

	1
	8	9
x	7	2
		8

Step 3: Multiply
2 x 8 = 16. Take 16 and add 1 from the previous step to get 17. Enter 17 at the bottom:

		8	9
x		7	2
	1	7	8

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		7	2
	1	7	8
+			0

Step 5: Multiply
7 x 9 = 63. Put 3 below the line and 6 as a reminder on top:

		6
		8	9
x		7	2
	1	7	8
+		3	0

Step 6: Multiply
7 x 8 = 56. Take 56 and add 6 from the previous step to get 62. Enter 62 at the bottom:

			8	9
x			7	2
		1	7	8
+	6	2	3	0

Step 7: Add to get answer
Add up the bottom two numbers (178 + 6230 = 6408) to get the answer:

			8	9
x			7	2
		1	7	8
+	6	2	3	0
=	6	4	0	8

The bottom line is the answer. Therefore, 89 times 72 equals:

6408
