Many Ways to Multiply

Multiplication is the adding together of multiple copies of the same number.  In other words, 3 multiplied times four (3 x 4) is the same as saying 4 + 4 + 4.  Multiplication, along with division, addition and subtraction, is one of the four main operations in mathematics.  Children begin learning to multiply in elementary school.

 

Following are the many ways to indicate the operation of multiplication:

 

3 x 4

 • 4

3 (4)

3*4

 

Multiplication of variables can also be indicated by placing them next to one another as in 3x or xy.

 

What is the most common way that you see multiplication indicated?  Does this change as you enter more sophisticated math classes?  Why do you think this is so?  Where have you commonly seen the asterisk used?
