 +You can make arrays in bash with "​declare"​ (-a makes a normal indexed array, while -A makes an associative array)\\ 
 +They work quite normally as compared to other languages.\\ 
 +When you call an array with a '​*'​ or '​@'​ as the index, it will expand the entire array (all of the values)\\ 
 +The "​let"​ command allows you to do integer math in your variable assignments as well as use a var's old value in calculating its new value.\\ 
 +I.E. "let total=total+value"​\\ 
 +But when non integers are concerned you need to echo the operation into "bc -lq" via a pipe\\
