How to calculate 46 multiplied by 45

How to calculate 46 multiplied by 45 using long multiplication. Here is step-by-step how to calculate 46 times 45 using long multiplication:

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

	4	6
x	4	5

Step 2: Multiply
6 x 5 = 30. Put 0 below the line and 3 as a reminder on top:

	3
	4	6
x	4	5
		0

Step 3: Multiply
5 x 4 = 20. Take 20 and add 3 from the previous step to get 23. Enter 23 at the bottom:

		4	6
x		4	5
	2	3	0

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

		4	6
x		4	5
	2	3	0
+			0

Step 5: Multiply
4 x 6 = 24. Put 4 below the line and 2 as a reminder on top:

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

Step 6: Multiply
4 x 4 = 16. Take 16 and add 2 from the previous step to get 18. Enter 18 at the bottom:

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

Step 7: Add to get answer
Add up the bottom two numbers (230 + 1840 = 2070) to get the answer:

			4	6
x			4	5
		2	3	0
+	1	8	4	0
=	2	0	7	0

The bottom line is the answer. Therefore, 46 times 45 equals:

2070
