A program that you make (using the built-in TI-Basic language) will be saved when you close out of it. You will however lose it when you replace the batteries.

One measure you can take to preserve your program is to change only two batteries at a time. This will normally prevent the program from being erased.

Another thing you can do is archive the program. Press 2ND MEM (above +). Choose 2:Mem Mgmt/Del... and then 7:Prgm... Press ENTER next to the program to archive it (which will be indicated by a star). Archived programs will not be deleted when you change the batteries, but you cannot run them until they are unarchived.

Finally you can put your program in a group to preserve it. Press 2ND MEM and choose 8: Group. Create a new group and put your program in it. (You will need to put a least two pieces of data in a group.) Ungroup you group to use the program later. Groups can also be used to help store more information on your calculator.

Yes.

First, one most know how much land is owned by them in an established unit where the well is drilled. For illustration let's say one owns 20 acres of a 160 acre unit. Next through negotiations on the original oil lease we will know what percent of the production will go to the owner as royalty commonly expressed as 1/5 (a fifth),1/4 ( a quarter) or less, etc. Let's assume in this example the negotiated amount was 1/5.

20 acres over a 160 acre unit equals .125 times .20 (1/5) eguals .025 which will be the fractional ownership interest assuming that the 20 acres is 100% theirs.

Taking that .025 fractional owner interest times whatever that production sells for during a specific time period ( usually a month) will be what the owner will receive minus severance taxes. If the well produces 10000 barrels of crude valued and sold at $100. per barrel there will be $1,000,000 in sells times the .025 (fractional ownership interest = $25000 minus a severance tax going to this particular owner.

Leibniz's calculator could multiply and divide as well as add and subtract. The pascaline calculator could only add and subtract.

you select the number you want , click Inv, then press x^3 and click enter and you got the answer.

dim mismatch occurs when you are trying to multiply matrices whose dimensions are imcompatible or when you are comparing two lists of unequal lenght.

Calculators have helped us in so many ways. They have made it easier to solve problems in a shorter period of time. Usually it would take us a max of 5 min to solve a problem and now we just type in the problem and it gives us the answer. Yes, it has made us dumber because we now don't really know how to solve problems the manual way and because we're so accustomed to using a calculator. But calculators make it possible for us to to solve problems that were difficult for us to solve in the past.
