How to calculate 43 multiplied by 15

How to calculate 43 multiplied by 15 using long multiplication. Here is step-by-step how to calculate 43 times 15 using long multiplication:

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

	4	3
x	1	5

Step 2: Multiply
3 x 5 = 15. Put 5 below the line and 1 as a reminder on top:

	1
	4	3
x	1	5
		5

Step 3: Multiply
5 x 4 = 20. Take 20 and add 1 from the previous step to get 21. Enter 21 at the bottom:

		4	3
x		1	5
	2	1	5

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

		4	3
x		1	5
	2	1	5
+			0

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

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

Step 6: Multiply
1 x 4 = 4. Take 4 and add 0 from the previous step to get 4. Enter 4 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (215 + 430 = 645) to get the answer:

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

The bottom line is the answer. Therefore, 43 times 15 equals:

645
