Megamaths is an Educational programme about Maths that originally aired on BBC2 between 1996 and 2001. Each episode was 20 minutes long and was written by Maths Television Presenter Simon Davies. Other people that have been in the series are Liz Crowther and Annee Blott. Between 1996 and 1999 it was presented in a castle where there were the four card suites and jokers. There were two gargoyles at the front of the castle who spoke in rhyme. After megamaths ran for 3 series they decided to stop the castle idea and two presenters presented in a studio.
The fourth series, which was produced in 1998 (and the last to be set at the castle on Table Mountain), comprised five episodes focusing on units of measurement. Brimstone and Digit also underwent a second redesign for their final series by second new animators Blue Sunflower Animation, but their appearance was only slightly different to how they had appeared for the second and third series.
