Simple program to add two numbers and say them for my 5 y/o daughter.

laura-addition.sh

run() {
  Q1="Enter a first number:"
  echo $Q1
  say $Q1
  read A
  say $A
  Q2="Enter a second number $1:"
  echo $Q2
  say $Q2
  read B
  say $B
  RES=$(($A+$B))
  echo "Result:"
  ANSWER="$A + $B = $RES"
  echo $ANSWER
  say $ANSWER
  say "Did you know that $1?"
  sleep 1
  echo ""
  say "Play again!"
  run $1
}
Q1="What is your name?"
echo $Q1
say $Q1
read NAME
A1="Nice to meet you $NAME!"
echo $A1
say $A1
echo ""
run $NAME

I had to prepend this to make it work on Linux:

say() {
    espeak "$*" >/dev/null 2>&1
}

And install http://espeak.sourceforge.net/ (apt-get install espeak or pacman install espeak or ...)
