To improve calculation skills, consistent practice and repetition are crucial. Engaging in regular mathematical exercises helps reinforce neural pathways associated with arithmetic, enhancing both speed and accuracy. According to a study published in the Journal of Educational Psychology, individuals who practiced arithmetic problems for 20 minutes a day over a period of 8 weeks showed significant improvement in their calculation abilities compared to those who did not practice (Smith et al., 2019). This highlights the importance of regular practice in developing calculation skills.
