Why do we need to take these subjects and pass it..the long equation,.formula,square root,angle of the right triangle and whatsoever angle,and many more..How usefull this subjects are,especially to those courses that addition, subtraction,multiplication or division of their wages once they got a job after they graduate is what they only need..Im not really good at math subject..I remember failing on my Geometry subject when i was in 3rd year high school,good thing theres a summer class..and i passed it... now im at my 2nd year in college,been working hard now to pass my basic statistics,.and i've worked so hard to passed algebra and trigonometry last year..but untill now,cannot get a clear answer..why need to undergo through these?
