Flintoff’s farewell
Recently retired cricket all-rounder Andrew Flintoff was known as Freddie until a much-publicised incident with a pedalo gave rise to the new nickname Fredalo. In the sum shown, digits have been replaced by letters, different letters representing different digits. Since there are 11 different letters everything is in base 11. Use 0 to 9 as normal and X for the extra digit.What is the eight-digit number (still in base 11) represented by FLINTOFF?
