I'm thinking of setting up a sweatshop style accountancy firm that's staffed by 8 year olds - these kids will file your tax return and find a way of keeping your inheritance tax exempt in no time. The only downside of Times table rock stars is that they are full addicted - damn gamification to help kids learn - it works too well! #TTRS #legends #maths #speed
