How to calculate 72 multiplied by 31

How to calculate 72 multiplied by 31 using long multiplication. Here is step-by-step how to calculate 72 times 31 using long multiplication:

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

	7	2
x	3	1

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

	0
	7	2
x	3	1
		2

Step 3: Multiply
1 x 7 = 7. Take 7 and add 0 from the previous step to get 7. Enter 7 at the bottom:

	7	2
x	3	1
	7	2

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

	7	2
x	3	1
	7	2
+		0

Step 5: Multiply
3 x 2 = 6. Put 6 below the line and 0 as a reminder on top:

	0
	7	2
x	3	1
	7	2
+	6	0

Step 6: Multiply
3 x 7 = 21. Take 21 and add 0 from the previous step to get 21. Enter 21 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (72 + 2160 = 2232) to get the answer:

			7	2
x			3	1
			7	2
+	2	1	6	0
=	2	2	3	2

The bottom line is the answer. Therefore, 72 times 31 equals:

2232
