I roto i te mātai ahupūngao, he whārite pāngarau te ture tātai e whakaatu ana i te pānga o ētahi taurangi e rua, nui ake rānei. Hei tauira, ko te ture taketake a Einstein, E = mc2 (E = pūngao, m = papatipu, c = te tere o te aho i rō korekore).
In physics, a mathematical equation which shows the relationship between two or more variables. For example, Einstein’s basic formula for energy, E = mc2 (E = energy, m = mass, c = the speed of light in a vacuum).
