Mathematics a subject showing students difficulty. In schools using Cambridge syllabus calculators are used every time. But in schools using NECTA syllabus in Tanzania calculators are not allowed to be used except for form 5 and 6. This petition is to encourage the Tanzanian government to allow usage calculators. Because the use of calculators is making the world advance in mathematical technology but students in Tanzania are falling behind in technology. You might find students not knowing how to use scientific calculators And making many students spend a lot of time calculating manually hence failing the subject due to small errors or insufficient time.
