For 2-D Math

For a product containing numbers, implicit multiplication can be used only if the number occurs in the left-most position in the product. For products of numbers, use explicit multiplication (), entered by using the asterisk (*) symbol on your keyboard.

2-D Math input allows for implicit multiplication, that is, writing a multiplication operation without requiring a multiplication sign.

In general, use a space to imply multiplication.

The following examples use a space to imply multiplication.

Exceptions to this rule include cases where it is clear that only multiplication can be implied:

 =

 =

There are, however, exceptions. Note the results for 2d and 2e.

 =

This is because 2d and 2e are used in floating point notation such as  =  In general, it is advisable to use a space.
