lower mathematics

[RonButters at AOL.COM]

I don't understand DInIs's problem here. "A-squared" = "A times A." In
algebraic notion, one can write "A x A", "A[dot]A," or just "AA" to indicate
the square of "A." So why isn't "A2" exactly right (if the "2" is written as
a superscript)?

I know DInIs is a whiz at statistics, but has he forgotten lower math?

*****in reply to:

A2 (actually A+superscript 2) or "a-squared," somehow meant to mean
"AA." If they had come to The Moo U they would have learnt better math
skills. (If A=A, what squaring operation will yield the string AA? 0X0=0,
1X1=1, 2+2=4 ....).
