A kid who was struggling at school is now a maths genius after his mum taught him to use an ABACUS - which she says can help today's children.<br /><br />Dr Rashmi Mantri, 45, used the ancient technique she learned while growing up in India to tutor son Dhruv Maheshwari, 16, after school.<br /><br />She noticed Dhruv began struggling with maths in primary five and was worried he couldn’t do simple sums.<br /><br />But after just six days he began to take to the abacus and was transformed into a maths whizz – with his classmates parents even reaching out for help.<br /><br />Dhruv has now landed an apprenticeship at drinks firm Diageo and said his teachers would be shocked by his career choice after his maths struggles.<br /><br />And his mum is using her abacus tutoring to teach thousands of kids around the world.<br /><br />Proud mum-of-one Dr Mantri, from Glasgow, said: “My son went from zero to hero because of an abacus.<br /><br />“I never thought I would teach him using an abacus, but it was something I used as a child in India and it was always helpful.<br /><br />“He can use it much faster than a calculator.<br /><br />“His teacher saw him using the abacus and thought it was magic maths.<br /><br />“He was asked to perform at an assembly and then other parents started getting in touch to ask if I could help their children.”<br /><br />In 2016 Dr Mantri launched the British Youth International College (BYITC) and is now using her abacus tutoring to teach to thousands of kids around the world.<br /><br />IT specialist Dr Mantri said the humble abacus can be used for calculations into the trillions and kids enjoy learning on it because it’s like a game.<br /><br />“I think the success comes because children can touch and feel an abacus and visualise them.<br /><br />“They become a playing tool for younger children, it feels like a game.<br /><br />“My son wasn’t interested in maths or studies but since using an abacus his life has completely changed.<br /><br />“He is so confident now and I am so proud.”
