equations have bothered me so much since being at school. can someone in leymans terms and in less than five minits please teach me what they are about like a+b =x and so forth i never get what the letters stand for so when i see a equation on tv i can never get my head around it becuause i dont know what the letters stand for i know e=mc2 e stand for energy and m is mass i dont know what the c is and why it is squered but i it all falls to peices when i think of old school day equatons that said e x 6 = 7 sqaured so that e cant stand for enegery again? is it that you need to be told what the letters are first or are you sposed to work out what the letters mean yourself like a cryptogram!?
it would propell me to nasa equivalent science if i could work it out simply
