Also, I know that I tend to do some of the simplifying in an odd way, but it works out for me. I guess it's just the way I think. I have, in the past, deliberately tried to simplify them the way the online equation calculators do, but I find it easier to just do it the way that comes "naturally" for me. Provided I continue to get the correct answer, it works for me.

The stated math problem came out of the textbook. Some of the problems that follow also come up with similar answers (ie. 0=-136). It really has me confused. Simply because 0=0, therefore, the statement 0=-251 cannot be correct.

Incidentally, the instructor I have for this class is one of those "I don't care if you learn it or not - I still get paid" (her actual words) type of teachers. So, she really hasn't been much help. I have learned more from this forum than the class I am paying for.

It was a typo - the post showing my work is the correct problem. Sorry.

I am trying to figure this one out, but not having any luck. I have several problems that are similar to this one, so I really need to understand how to work it out.
I keep coming up with the answer 0x=-251. But I can't have a "0x" can I?
Thanks,
Charlie
Bobbym,
The education I have is one I picked up from years of dealing with people. I have actually spent the last 10 years in upper management for an international construction company. When dealing with people from many differring backgrounds, you learn to be polite. Also, I have spent a great deal of time online in the last 16 years, so I have a good understanding of "nettiquette".

Bob,
A GED is a Graduate Equivalency Diploma. Typically given to folks like me, who when they were young, made the mistake of not finishing high school and later wished to take the course and obtain the "equivalent" (in theory) of a diploma. In the US, you cannot attend college or a university without either a high school diploma or a GED.
And, I really am not that old. But from experiencing life without an education (a lot of menial labor jobs), I feel old physically. I was recently diagnosed with three ruptured discs in my neck from decades of physical labor that have caught up with me. So, now I have been pretty much forced into a decision to go back to school and work towards another career field. I have chosen the IT (information technology) field, as I seem to have a natural aptitude for it.
Thanks again for your help. Hopefully, I can return the favor to someone else here in the future.
Charlie
Bob,
Thanks for your kind reply. I really appreciate your help. As I said, it has been entirely too many years since I have sat in a classroom. I am probably 25 years older than my instructor. Once upon a time, I actually taught a high school GED class, so I should have been able to figure it out. But, lately, I seem to be discovering that I suffer from a progressive case of CRS (Can't Remember S&%t).
Thamk You,
Charlie
Okay, I understand now. I was writing the problem out with the division included (as opposed to calculating the top number first and then the bottom number and writing it out as a fraction). I can figure it out now. Incidentally, you had a typo in the problem which leads to a wrong answer - you had (9+4) squared, when it should have been (9+2) squared), but, I didn't actually want the answer - I wanted to understand the principal involed in solving it, which you showed perfectly clearly. Thanks. The answer, as I figure it should be 1/121, correct?
Charlie
Hopefully, someone can help me. I just started back to college after 30+ years and was given homework simplifying expressions. I haven't had any problem until I hit the following problem. Hopefully, someone can help me out with it. I have several more like it, so I just need to understand how to solve it and I can continue on my own.
The problem is:
5*2-3exp2
_________
[3exp2 - (-2)]exp2
I will try to write it out:
5 time 2 minus 3 squared over bracketed 3 squared minus negative 2 (in parenthesis) Bracket squared
I am looking at the problem rewritten out as this:
5*2-3exp2 divided by [3exp2 - (-2_]exp2
But that doesn't work out right using the order of operations.
I am at a complete standstill on this and I have been trying to figure it out for so long that the numbers are starting to get mixed up in my head.
Thanks in advance for any help.
Charlie
