Hi Guys,

It seems to calculate the result but instead of displaying like i want it too it loops back to the start.

Any hints would be greatly appreciated.

#/bin/sh

echo " \"Welcome\" to the most awsome calc evar"
echo "1) Addition"	#add two Numbers
echo "2) Subtract"	#subtract two numbers
echo "3) Multiply"	#multiply two numbers
echo "4) Divide"	#divide two numbers
echo "5) Factorial"	#Factorial two numbers
echo "6) Campare"	#Campare two numbers
echo "7) EXIT"		#exit the calculator
read CAL			#get number for selection on CALC
while [ $CAL != 7 ]
#if CAL = to 7 will exit, if not continue next line
do
case $CAL in			#database arrays
"1")
	echo "You've picked Additions"
	echo "Choose a number"
	read NUM1
	echo "Choose a another number to add to the first number"
	read NUM2
	VALUE=$(($NUM2+$NUM1))
	;;
"2")	echo "You've picked Subtract"
	echo "Choose a number"
	read NUM1
	echo "Choose a another number to Subtract to the first number"
	read NUM2
	VALUE=$(($NUM1-$NUM2))
	;;
"3")	echo "You've picked Multiply"
	echo "Choose a number"
	read NUM1
	echo "Choose a another to multiply"
	read NUM2
	VALUE=$(($NUM1*$NUM2))
	;;
"4")	echo "You've picked Divide"
	echo "Choose a number"
	read NUM1
	echo "Choose a another to divide the first number"
	read NUM2
	VALUE=$(($NUM1/$NUM2))
	;;
"5")    echo "You've picked Factorial"
	read NUM	# get a number
	FOR=1
	FOR=$(($FOR*$NUM))	# FOR TIME NUM
	NUM=$(($NUM-1))		# TAKE 1 OFF NUM
	FOR=$(($FOR*$NUM))	#FOR TIMES WITH NUM
	NUM=$(($NUM-1))		#TAKE 1 OFF NUM
	while [ $NUM -gt 1 ]	# LOOP UNTIL NUM = 1 
	do
	FOR=$(($FOR*$NUM))
	#times End by nu
	NUM=$(($NUM-1))
	#takes 1 off NUM
	done
	echo "And the answer is $FOR"
	
	;;
"6") 	echo "You've picked Compare"
	echo "Pick a number"			#ask number
	read NUM1			#ask another number
	echo "Pick another number"
	read NUM2
	if [ $NUM1 -eq $NUM2 ]		#if NUM1 = NUM2
	then
	 echo "First Number is equal to Second Number"	#show anwser NUM1=NUM2
	else			#or
if [ $NUM1 -lt $NUM2 ]		#NUM1 less less than NUM2
then	
echo "First Number is less then the Second Number"		#show answer A less B
else
echo "First Number is Greater than Second Number"			#or answer is A is Greater than B
fi
fi
	;;
*)

echo "YOU ENTERED INVAILD OPTIONS"
echo "PLEASE TRY AGAIN"
	;;
esac				#show answer

echo $VALUE

clear		
		#space
echo "\"Welcome\" to the Magic CALC"
echo "1) Addition"	#add two Numbers
echo "2) Subtract"	#subtract two numbers
echo "3) Multiply"	#multiply two numbers

You just need to add a pause after displaying the answer.

So after line 86 where you do  echo $VALUE, add

read -p "Press Enter to continue..."
