Alternatively, you can use case/esac without worrying about different styles of if/else

case "$num1$num2" in
 "00" ) echo "ok";;
 * ) echo "not ok";;
esac

In POSIX shell you can do:

#!/bin/sh

if [ $num1 -eq 0 -a $num2 -eq 0 ]; then
  echo "ok"
fi

If you can use bash then you can do:

#!/bin/bash

if (( num1 == 0 && num2 == 0)); then
  echo "ok"
fi

If you want to save keystrokes and don't mind being a bit cryptic you could also do:

#!/bin/bash

if ! (( num1 | num2 )); then
  echo "ok"
fi
