My Journey With Mathematics

harpazo said:
A few things about me.

1. My days to "MAKE IT" in life are over.

2. I am 55 years old.

3. I am not learning advanced math to become a teacher. If I can somehow land a tutor job, and make extra money, terrific! If not, who cares, right?

4. Mathematics is a hobby and nothing more.

5. I put all other hobbies aside to do math, including Bible study time. This is not a good idea.

6. I had to give up playing guitar to avoid trouble with roommates. You see, I don't have my own place. Rent is out of control in NYC.

7. Currently on furlough WITHOUT PAY due to COVID-19. I hope to be back to work in the Fall.

55 is just the beginning.
The mix of music and math sounds just great.
You can play guitar outside.
 
I don't like the sound of that, "my life is over at 55"!! My dad is 80 and he told me he has another 30 years to go before his life is over. By that reckoning then I have another 60 years to go at least. If I'm lucky I'll of scratched the surface of understanding some math's, maybe?

How many people are lucky enough to reach 80? Does your dad know what his physical will be 30 years from now? I am realistic not negative. I admire his view of life but aging is no joke. I am 55 and women surely let me know as soon as I step outside.

I am totally ignored by women. Conclusion: 55 is not 25 years old. By the way, your username tells me that you are good at probability. Is this true? I will need help with probability later in my self-studies. Probability applications are a bit fuzzy to most people.

Many reach the 80th today. If you reach it, the rest is a question of positive attitude.

Search engines are good, for answering questions like that. Here are some probabilities (reported by the Social Security Administration) based on current age, using 2019 data.

For 50-year-olds*, about 57% of males and 67% of females will live into their 80s.

For 60-year-olds, about 62% of males and 71% of females will live into their 80s.

For newborns, about 64% of males and 73% of females will live into their 80s.

*Due to the Korean and Vietnam wars, results for this age group are skewed downward.

How many people are lucky enough to reach 80?

A lot of people live until they are in their 80's or older. The consensus these days seems to suggest that more and more people are living longer now that they ever did previously. There are many reasons for this too.

I am 55 and women surely let me know as soon as I step outside.

Forget that idea that you are too old to attract women, that is not what women would be thinking. Example, my dad is 80 years old and my oldest sister is 56. She is in Christie's at the moment in ICU on a ventilator because of serious reactions to chemo. A female nurse told my younger sister that she fancied my dad. He is 80 not 55.

I went shopping in the local Sainsbury's store and got chatting to the ladies on the tills over a period of time. One lady who works there told me that one of the ladies on the check-outs wants to date me. I'm 55. The point being, it's not what you think about yourself that matters but what women think about you, if you want a relationship.

By the way, your username tells me that you are good at probability. Is this true?

Probably.

Good answers. You are the guy to help with probability basics. Look for questions in the probability forum from time to time.

How much can a person who is 80 or higher do in terms of physical activities? If I cannot use the bathroom by myself, is that not the end of life?

Have you ever seen a person who is 80 or older? In 1995, I worked security at an old folks home in Queens, NY. During my rounds, I would often see old folks lying on their beds looking at the ceiling probably thinking about their youth. Not fun, dude.

Clearly, the answer is a function of groups. If you're really interested in seeing what's possible, go to AARP's website and peruse some of their bulletins and magazines. Older people are doing amazing things.

My 87-year-old maternal grandmother would climb a ladder onto the roof, to adjust her TV antenna after windstorms. She'd also drive out to the farm and dig small ditches, to divert rainwater.

Until recently, my 93-year-old mom would drive herself to hair appointments, the grocery store and to meet the casino shuttle.

In my 20s, I remember meeting a 91-year-old man who'd retired from the ad agency where I worked. Once a week, the gentleman would drive 60 miles to pick up billing worksheets that I'd prepared. He would take them home and type client invoices (using a typewriter from the 1940s). In seven years, I never saw a single error in his work. The guy was an inspiration, to me.

Regardless of age, adult life is what a person makes it, with each individual adapting to their own circumstances.

… If I cannot use the bathroom by myself, is that not the end of life?

Yes, it is not the end of life. Attitude plays a large role, in quality-of-life issues for older people. If you're worrying about what life may hold for you, then you could start working to improve your attitude now. Growing old means change and adapting to change.

I've interacted with more 80+ people than I can remember, having spent 15 years working in emergency medicine and 25 years providing services to honored citizens as a volunteer.

By the way, the correct word to use above is 'possibly', not 'probably'.

Hi everyone. I joined this site for help with my self-study of mathematics. Read one through 7 below.

1. I am not a classroom student. My college days ended in 1994.

2. I enjoy solving textbook math problems in the way others enjoy crossword puzzles, painting, drawing, etc.

3. I am a self-study "student" of mathematics. I decided to review math learned long ago and hopefully learn new material through the help of math professionals here.

4. I don't write in LaTex form. I simply upload math work down on paper unless it is a word problem.

5. I do show my effort and work depending on the problem at hand. If I don't know how to begin to answer a particular textbook math problem, I will ask for one or two hints or help getting started.

6. Current reviewing College Algebra. I am in Chapter 1 Section 7 aka Rational Expressions. I plan to go through the entire textbook. So, please come along for the ride.

7. Obviously, I will not post EVERY SINGLE PROBLEM in the textbook. I will only post problems for which the author (Michael Sullivan) did not provide an example for or simply a problem that I find interestingly challenging.

My name is Feliz. I hope to have a positive learning experience here.

Thanks.

That is an excellent list! Please add:

8. With Every problem posted,
I'll include what/how I have tried to solve it. And​
​
Why do I think my-way is not working​

My editing time is over. However, your suggestion for number 8 is also included in my reply here.
 
Beer induced suggestion follows.

I found the following college algebra website that appears to be user-friendly. Definitely easier than any college algebra textbook I could find. I will be learning and reviewing college algebra material using the material at the following website. Tell me what you think. Good site? Bad site? OK site?


Starting tomorrow, I will use the following website to review and learn College Algebra:

I have decided that the Michael Sullivan textbook is the right way to learn College Algebra or any other course. So, I downloaded one of his textbooks (copyright 2017) to begin using right away.
