What happens in here? something wrong with
if ["$answer1" -eq "$((i*j))"]
This just compares whatever their input is with the actual answer.

I've checked that and both values come out correct. If you add the bolded statements to it, you'll see that the values come out correctly, so it should just be comparing them.

Code:
 
#!/bin/bash
i=1
while [ $i -le 10 ]; do
    j=1
    while [ $j -le 10 ]; do
      echo "$i * $j = "  
      read answer1
      echo "answer1 is... $answer1"
     echo "calculation is... $((i*j))"
      if ["$answer1" -eq "$((i*j))"]
      then
        echo 'Right!'
        ((j+=1))
      else
        echo 'Wrong!' 
     fi     
    done
    ((i+=1))
done

I'm not sure why you're getting that error... pretty awfully non-descript. I'll take a look at your second script and see if we can manage to get that to work how you want it.
