math proficiency

marikina science high school students are not really math proficient. i guess your wondering why. from what we know: when you subtract five from two hundred nine you get none, as in zero, as in null etc. when you get the derivative of two hundred nine, you get one. likewise, when you get the anti-derivative of one, you get two hundred nine. we are not really sure of what exponents really are so are the base and the power.
