Assertion:
"The indefinite articles in the English language are not always used properly."
Proof:
See this question. It should be "What is anexample of a proof?".
Therefore, whoever posted the question did not use the indefinite article correctly in the question. Thus, there is at least one person who did not, on at least one occasion, use the indefinite article properly. Therefore, the statement is proved to be correct.
A proof is a very abstract thing. You can write a formal proof or an informal proof. An example of a formal proof is a paragraph proof. In a paragraph proof you use a lot of deductive reasoning. So in a paragraph you would explain why something can be done using postulates, theorems, definitions and properties. An example of an informal proof is a two-column proof. In a two-column proof you have two columns. One is labeled Statements and the other is labeled Reasons. On the statements side you write the steps you would use to prove or solve the problem and on the "reasons" side you explain your statement with a theorem, definition, postulate or property. Proofs are very difficult. You may want to consult a math teacher for help.
Proof-like coins have features similar to a proof coin, but may not fit the definition of a proof (for example, they may not be double struck). Proof-like coins have mirrored fields (you should be able to see your reflection in the spots of the coin where there is no design) and are generally of higher quality than coins produced for circulation.
One half of the proof for alcohol is the measurement of its alcohol content, which is expressed as a percentage of alcohol by volume (ABV). To calculate proof, the ABV percentage is multiplied by two; for example, a beverage with 40% ABV is 80 proof. This system helps consumers understand the strength of alcoholic beverages.
A conclusion is a result that can be drawn from a scientific experiment A reason is an example of proof why or how you know the conclusion is right
It is possible to draw a straight line from any point to any other point.
The "burden of proof" is the amount of evidence and/or testimony necessary to convince the court or jury of your guilt.
Stainless steel is an example of a metal that is rust-proof. It contains chromium, which forms a protective layer on the surface of the metal that prevents it from rusting.
Something soundproof or near sound proof. A vacuum, for example.
What proof do you have? Your inference is wrong, Mr. Holmes.
The noun 'proof' is an uncountable noun except as a word for a printing proof or a photographic proof.The plural form of the noun 'proof' is proofs.The plural possessive form is proofs'.Example: the proofs' printout is eight pages.

Many distilled beverages are 100 rather than 80 proof or are available as both 80 and 100 proof. Smirnoff makes a 100 proof vodka, for example, as well as 80 proof, but so do many other producers.
There are a number of online stores that sell proof sets. The web domains "LittleTonCoin" and "GoldenEagleCoin," for example, are known to sell these sets.

Anything that requires money is a proof of cash.. the payment for the expenses, or anything you get through the use money is a proof of cash: buying, use of transportation expenses, paying for the services rendered, collection of income etc.

A fire proof box may be used to store very valuable items and documents to protect them in case of fire in the home or business. For example, deeds, passports and wills may be stored in a fire proof box.
