If using a calculator (Casio fx-82MS) then you press mode (top right) until you get to the screen saying Fix, Sci and Norm; You press Sci (2) and then it says Sci 0-9? you press how ever many numbers you are trying to find the standard form e.g if you were trying to find the standard index form (SIF) of 4233232 you would choose 7, because there are seven numbers but in our case we would choose 1 but if you were adding 8 and 2 you would choose two. and you should get this number when adding 8 and 2.. 10 and it should automaticly be in SIF. =1.0x10(to the power of 01) :)
