if you want proven mathematic formulas how to pay off 30-year loan in 10 years, I'll share the tips, $100/hr ?

Many persons, myself included, warned people to ACT UPON THE OPPORTUNATIES during those times with all haste because we knew with mathematical certainty it would not last.   

We know with mathematical certainty that's a unique time opportunity because with reproduction costs so much more, it's only a time cycle as that satellite market pricing will rapidly appreciate, because it's below "gravity". 

Calculating a cash flow requires a mathematical equation and it goes up and down based on the inputs.  

Hi @Eric Li,Mentality: You and I are very much alike; you are very analytical, which is a gift, but it also can trick you into thinking you can outsmart the future and mathematically win at investing. 

I also had degrees in Mathematics, Computer Science and Physics (minor) and thought that if he could execute, he would own the industry. 

Bachelors and Master's in Petroleum Engineering with a minor in Mechanical Engineering and a minor in Mathematics.

There are plenty of metrics I've seen people use that determine the most prudent time to sell mathematically based on cap rate, COC, ROI, IRR, etc. but the big x-factor in these calculations is future performance based on both appreciation and rent increases, which haven't been following a predictable linear pattern lately at all.

That is just a mathematical fact.I hope this is helpful.

It can not visit a website and determine using emotions and logic and user intent to see which website is good.So it uses a mathematical scoring formula that will score certain metric and then at the end, it adds up all these metrics to assign a score to a website for a specific key phrase.Let me give you an example.Back in the day when we didn't have all the fancy technology in cars, you needed to go 20 MPH to take a bend in the road because of the limited suspension technology etc. etc.
