communication occurs. However‚ there may be many misperceptions that mathematics is a language. One may argue that one can utilize numbers to represent certain letters in the alphabet‚ for example‚ a= 1‚ b = 2‚ c = 3. It is just using numbers‚ to represent a language. However‚ this is not mathematics. Numbers themselves can be a language‚ however numbers are just symbols. Numbers are not mathematics. Do we use mathematics to communicate? No. This is because mathematics is not a language‚ it is a process

Simple Random Sampling The simplest form of random sampling is called simple random sampling. • • Objective: To select n units out of N such that each NCn has an equal chance of being selected. Procedure: Use a table of random numbers‚ a computer random number generator or a mechanical device

completed by the English mathematician Andrew Wiles in 1994. To conclude or even to conjecture that a statement is true merely by experimental evidence can be dangerous. For instance‚ one might conjecture that n 2 − n + 41 is prime for all natural numbers n. One can easily verify this: when n = 1‚ n 2 − n + 41 = 41 is prime; when n = 2‚ n 2 − n + 41 = 43 is prime‚ and so on. Even if one continues the experiment until n = 10‚ or even n = 20‚ one would not be able to find a counter-example. However
