“…The basic abilities that can help the learning process run well are problem-solving skills that can combine the information obtained in order to be able to find solutions to the problems given by using the right method so that they can achieve the targets to be achieved (Ince, 2018;Maisyaroh Agsya et al, 2019;Nisa et al, 2020;Purnama et al, 2020;Suryani et al, 2020). Based on this, problem-solving skills are the basis of other abilities, namely mathematical reasoning abilities, because when students solve problems, they must also be able to present, and model problems until they can finally find a solution (Cerda et al, 2017). If students' problem-solving ability is maximized, then they will be able to solve a problem well, but some students in Indonesia have low problem-solving abilities, especially in applying them to problem solving (Akbar et al, 2017;Suraji et al, 2017).…”
