Goh Zhi Hwee managed to multiply mentally two 10-digit numbers generated by an online random number generator. He was only allowed to write down on paper the two numbers and then the full answer. The 19-digit answer was verified using an online full-precision calculator. This was tested at RoomKiosk Tanjong Pagar on 26 Nov 2024. Goh, 27, is a data scientist working in cybersecurity.
