Will any one help me getting the sanskrit sloka supposed to be told by Namagiri Thayar to Srinivasa Ramanujam?

Goddess Namagiri (consort of Narasimhan God) at Namakkal, Tamilnadu had blessed mathematician Srinivasan Ramanujan with a sloka to solve mathematical problems. It is believed that if children chant that sloka daily, will shine in mathematics.
