when do you need to use pythagoras and trigonometorey in your later life becasue i really feel like what is the point to be getting taught this if you dont need it. but i do undertand how you need additon and subtraction but they are the only ones you need as for instance imagine you was at a corner shop you wont be needing to work out a similtaneous equation for how much you have to pay or the fraction that you are going to eat or drink of the item you have just bought. this really annoy me so much!!!!!!!!!!
