The study entitled "Comparative Research: The Use of Local Strategy and Foreign Strategy on Mental Arithmetic Calculation," intended to examine two methods of mental arithmetic utilized by Calumpang National High School students in Grade 7. The mental abacus was the foreign strategy, and the place value strategy was the local one. Using a pre-test and post-test with randomly selected 30 students for each strategy, the study sought to determine how well students performed in terms of speed and accuracy when performing mental arithmetic. he significant differences between the two techniques were ascertained using the Paired T-test. The study showed that while there were no significant differences between the two strategies in addition and subtraction, there were significant difference in multiplication and division. The findings bared that the effectiveness between the local and foreign strategy on mental arithmetic calculation is considered to be partially significant.
