Today is the first day of term 3 for secondary, JC and poly students, hope every student has a great day at school (though some of my students have exams today). Hope they find the exams/tests easy.:)
Here is a challenging Additional Mathematics question for you to try (Sec. 3/4 students should be able to do it):
If A, B and C are angles of a triangle, prove that tan A + tan B + tan C = tan A tan B tan C.
