Mathematical Loop
Hi, I'm creating a loop that allows the user to enter any number, then their choice of operator and then another number until their operator choice is equal to =
But I am getting an error saying integer expression expected. Any explanation on why this is happening?

Code:
echo "Please enter a number"
read userNumber | bc
endOfSum==
echo "Please enter the operator you would like to use (+, -, *, /)"
read userOperator
until [ $userNextOperator -eq $endOfSum ]
        do
                echo "Please enter your next number"
                read userNextNumber
                echo "Enter your operation (+, -, x, /, =)"
                read userNextOperator
                userTotal=$userNumber $userNextOperator $userNextNumber
        done
echo "The total is $userTotal"
