anyone know of a good book for manufacturing or industrial physics? thank you for any suggestions.

thank you all for the help, I am not majorly into mathematics, pre-calculus is all I am up to and then ill be learning calculus afterwards, just trying to get a more elaborative understanding of basic math before i build on it, thank you.

ya, that sort of problem, just wondering why the denominator gets dropped and is no longer written as a fraction, i know how to do the math, just understanding technicality of it eludes me, just would mind knowing the logic behind it, perhaps i was tired the day i learned that math lol i don't know.

nope that's a different situation, i mean when you get a same denominator for each side of the equation then solve

well I am still learning personally, from my experience there is no quick way to learn math unless your a genius, you just have to gain a general understanding of what math is, then start from the bottom and work your way up plus, if you rush learning math you may not be building a proper...

i see your ability to factor is past my ability lol, well I am still learning, so its alright, nice post.

hmm, i guess that is where my confusion is, i assumed that the "implied" was a real disappearance, so other than formula manipulation and division of fractions (1/3 to .333 for example) you can't make a fraction denominator really disappear, so even when you make a common denominator it is still...

ya, that sort of thing, why is it the denominator can be disregarded but on other equations it has to stay even when the whole equation is on same terms, just would like some explanation of the technicality of it, math theory of it i suppose

nope :( wish i had a sample, just something that came to mind that i don't elaborately understand but am able to do, very frustrating thanks all for helping, ill let you know if i run across a good sample of a time when you don't need the denominator once all terms have been given the same...

i don't have one atm unfortunately, ahwell thanks anyways

but sometimes when you find a common denominator for all terms of both sides of the equal sign then the denominators dissapear very frustrating having holes in my understanding in some basic math, but it happens, knowledge fades sometimes

that polynomial doesn't factor that i can see

what about 5A/5+7A/10=9A/10 (just a random question, probably doesn't equate) im just wondering the general rule, all i know is how to do it in each instance, sucks to move on and be missing a hole here and there, just want to know why sometimes the denominator stays and sometimes when the...

hello, I am pretty up on most pre-calculus math but i have a bit of confusion when you raise a denominator of an equation so all numerators are on the same level, at what point does the denominator disappear and at what point does it stay after this activity? eg. 4/4+5/2+6/4=4/2 =...
