Sorry for repeating my question.

$tab_T1[$element]=`expr ${tab2[$element]} - ${tab1[$element]}`

do echo "$element"
done

echo ${#tab_T1[*]}

line 56: syntax error near unexpected token `$tab_T1[$element]=`expr ${tab2[$element]} - ${tab1[$element]} line 56: `$tab_T1[$element]=`expr ${tab2[$element]} - ${tab1[$element]}`'
