How to calculate 84 multiplied by 31

How to calculate 84 multiplied by 31 using long multiplication. Here is step-by-step how to calculate 84 times 31 using long multiplication:

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

	8	4
x	3	1

Step 2: Multiply
4 x 1 = 4. Put 4 below the line and 0 as a reminder on top:

	0
	8	4
x	3	1
		4

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	4
x	3	1
	8	4

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

	8	4
x	3	1
	8	4
+		0

Step 5: Multiply
3 x 4 = 12. Put 2 below the line and 1 as a reminder on top:

	1
	8	4
x	3	1
	8	4
+	2	0

Step 6: Multiply
3 x 8 = 24. Take 24 and add 1 from the previous step to get 25. Enter 25 at the bottom:

			8	4
x			3	1
			8	4
+	2	5	2	0

Step 7: Add to get answer
Add up the bottom two numbers (84 + 2520 = 2604) to get the answer:

			8	4
x			3	1
			8	4
+	2	5	2	0
=	2	6	0	4

The bottom line is the answer. Therefore, 84 times 31 equals:

2604
