M3

was looking at my wife timetable for darjah 2 azam. saw this word:

M3

it is a short form for mathematics.

yeah..just recalled. i used to use the same shortform. but still try to recall why it is called M3

I know that kemahiran 3M is membaca, menulis, mengira. but M3?

sapa tau kenapa M3? even cikgu haida pun tak tau kenapa..
