Note: In most shells, the asterisk must be escaped with a backslash to prevent it from being interpreted as a wildcard. expr 937808300 / 932955077 Result: 1

The expr utility requires an operator to perform a calculation. Without an operator (like + , - , * , or / ), the command will typically return an error or simply print the first number, depending on the specific shell environment. Potential Calculations

expr treats each number and operator as a separate argument. You must include spaces (e.g., 9 + 5 , not 9+5 ).

In modern scripting (like Bash), it is often more efficient to use Arithmetic Expansion —for example: $((937808300 + 932955077)) .
