How to calculate 99 multiplied by 40

How to calculate 99 multiplied by 40 using long multiplication. Here is step-by-step how to calculate 99 times 40 using long multiplication:

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

	9	9
x	4	0

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

	0
	9	9
x	4	0
		0

Step 3: Multiply
0 x 9 = 0. Take 0 and add 0 from the previous step to get 0. Enter 0 at the bottom:

	9	9
x	4	0
	0	0

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	4	0
	0	0
+		0

Step 5: Multiply
4 x 9 = 36. Put 6 below the line and 3 as a reminder on top:

Step 6: 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			4	0
			0	0
+	3	9	6	0

Step 7: Add to get answer
Add up the bottom two numbers (0 + 3960 = 3960) to get the answer:

			9	9
x			4	0
			0	0
+	3	9	6	0
=	3	9	6	0

The bottom line is the answer. Therefore, 99 times 40 equals:

3960
