This study investigated the effect of use of scientific calculators on Yamfo Anglican Senior High School Students mathematical achievement. The main instrument were tests (pre-test and post-test) and questionnaire designed to collect data which were analyzed using quantitative methods and qualitative method. The sample size for the study was 41 students. A dependent sample t-test was conducted to compare the difference between students’ ability to solve mathematical questions by using calculator and not using calculator. The results indicated there was a statistically significant difference in students’ performances in solving mathematical questions in the first achievement test (M = 40.78, SD = 17.984) and second achievement test (M = 51.58, SD = 17.984) respectively [t (39) = 25.206, p=.000]. This result implied the intervention was successful; the students improved in their understanding of the use of the scientific calculator and improved their computational skills in mathematics such as sequence of operations, approximations, application of concepts and the appropriate use of parenthesis. Students most errors in the pre – test were on parenthesis, followed by operational sequence, approximations and concept applications which were overcome by the intervention.
