This was a request for edits to the tutorial Operators: arithmetic and otherwise

Yes, Splinky's at it again, proofreading tutorials like your high school english teacher. Nobody take offense, please. I'm just tryin' to help out.

First, the technical stuff.

"$3" should just be "3" in $b x=3;    #$b=$b x $3 $b is now equal to "xxx";

In the statement, "You can also use an and to allow something to execute only if the first criteria evaluates to 0", that "0" should be "true". Also, that statement should probably end in a period, not a semicolon.

And now, the picky grammar stuff.

"Assignment simply set values" should be "Assignment simply sets variables"

Need some commas in the "Autoincrement and Autodecrement" section. It's easier to replace the whole paragraph than try to explain where the commas should go, so:

These operators simply add or subtract one from a given variable. If the operator comes before the variable, the value of the variable after the operation is returned. If the operation comes after the variable, the value before the operation is returned. For example

And finally, misspellings.

"mulitply" should be "multiplication"
"notdefined" should be "not defined"

*Woof*
