I have just tried to insert mathematical symbols in a maths question i am writing out and am unable to find them. The only symbols i can find are limited to Greek letters and a few symbols such as = infinite, strictly less than, strictly greater than. I need to be able to insert other maths symbols which i am able to find if I go into the edit on the symbols box but cannot do anything once i find the sign-symbol i need. Any ideas would be very gratefully accepted as always. thanks in advance.
