New servers, hooraaaay! More bandwidth, more power.
which calculator is allowed in math 0580 IGCSE exam??fx-991ES or fx-85ES ??if both of them are allowed, then choose the two options (in the poll)our math teacher said that we cant use fx991ES, so i just want to make sure.
not about working, but wat if the calculator is not allowed???then i will be disqualified, right?
fx 991es can solve quadratic equations.and equations of the form:anX + bnY + cnZ = dnanX + bnY= cnax^3 + bx^2 + cx +d = 0
actually i have both of them, i bought 85es cuz our teacher said that we cant use 991es, but we can use 85es.but i think that 991es isnt allowed in AS and A, am i right GG ?
now the question, 991es allowed?answer with YES , YUP, Yea, or NO, Nope, nah,
i have the 991 ES and i used in my IGCSE exams,cant i use in the AS?
