Ethan Kirstein is no ordinary 12 year old. He is from A+Students by CMATHS and will be representing South Africa at the Mental Maths World Cup in Germany, and the PAMA Global Competition in South Korea later on in the year. Gareth challenges him to an addition challenge, but there is only one clear winner here!
