2.9) More On The Equal Sign (cont'd)

As an example of a statement that makes sense in programming but is nonsense in math, consider.

A=10.0
A=A+1.0

In programming, when the computer comes to this bit of the program it will first use the value of 10.0 to assign it to A. On the next line it works out the RHS first so that A=10.0 is added to 1.0 to become 11.0 and it will be assigned to the LHS variable A. So now A=11.0.
