How to calculate 99 multiplied by 84

How to calculate 99 multiplied by 84 using long multiplication. Here is step-by-step how to calculate 99 times 84 using long multiplication:

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

	9	9
x	8	4

Step 2: Multiply
9 x 4 = 36. Put 6 below the line and 3 as a reminder on top:

	3
	9	9
x	8	4
		6

Step 3: Multiply
4 x 9 = 36. Take 36 and add 3 from the previous step to get 39. Enter 39 at the bottom:

		9	9
x		8	4
	3	9	6

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

		9	9
x		8	4
	3	9	6
+			0

Step 5: Multiply
8 x 9 = 72. Put 2 below the line and 7 as a reminder on top:

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

Step 6: Multiply
8 x 9 = 72. Take 72 and add 7 from the previous step to get 79. Enter 79 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (396 + 7920 = 8316) to get the answer:

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

The bottom line is the answer. Therefore, 99 times 84 equals:

8316
