It's really simple once you get the hang of it. Here, I'll show you how.
Example:
24 This is 2 digit by 2 digit.
x10
First you have to multiply 4x0 equals 0.
Then you put the 0 under the ones place. Like this: 24
x10
0
After that, you multiply 0x2 equals 0. Then you put another
zero under the tens place. Like this: 24
x10
00
Time for step three! Ok, then you just add a zero under the ones place.
(Anytime you multiple two digit by two digit, you ALWAYS have to put another
zero under the ones place like this: 24
x10
00
0
Right now I have to leave and go home. I will finish this lesson tomorrow. Bye!!

Multiplication in general is important; not just 2-digit numbers.
Use a calculator... Even your computer has one built in...

In any two-digit multiplication sum, for example, 3 x 2 = 6, the first digit is called the multiplier, the second digit is called a multiplicand, and the third digit, the answer, is the product.
A one digit multiplication problem is one in which the numerals being multiplied have only one digit. Examples would include: 6x2 or 5x3 or 7x4 or 1x8. (These are just a few examples. The list of all the possible one digit multiplication problems would be very long.) A two digit multiplication problem is one in which the numbers being multiplied have two digits. Examples would include: 12x43 or 16x21 or 75x23.
