Notation. We use 
- as a prefix operator with priority 358 corresponding to applying term 
minus_SNo.
 
Notation. We use 
+ as an infix operator with priority 360 and which associates to the right corresponding to applying term 
add_SNo.
 
Notation. We use 
* as an infix operator with priority 355 and which associates to the right corresponding to applying term 
mul_SNo.
 
Notation. We use 
< as an infix operator with priority 490 and no associativity corresponding to applying term 
SNoLt.
 
Notation. We use 
<= as an infix operator with priority 490 and no associativity corresponding to applying term 
SNoLe.
