 The repl has the following syntax (It's work in progress, new capabilities will be added)
 * arithmetic expressions:
-  * add, subtract, divide, multiply
-* variable declaration eg: ```a = 1```
+  * add(+), subtract(-), divide(/), multiply(*) on scalars, vectors and matrices. 
+* variable declaration eg: ```a = 1 + 2```
 * ```remove(x)``` removes bindings (when it's an object (eg vector), removes it from the matrix)
-* ```remove(@n)``` removes an object using it's assigned index (```n``` is a number) 
+* ```remove(@n)``` removes an object using it's assigned index (```n``` is a number)
+  * By the way, values can be bound to a name (assigned to a variable), but you can always also refer to them using their id, using : ```@n```
+  * so ```a = vector(1,1)```
