Empirical Formula and Molecular Formula
... The empirical formula is the simplest formula that exists in simplest whole numbered ratios. That is, it gives the number of moles of each element present in the lowest possible numbers. If you know the number of moles of each element, then you can write the empirical formula. Let us say that 2 mole ...

... Example 12: Write a variable expression for ‘the difference between 45 and a number’ and simplify if you can. The number: x 45 - x which cannot be simplified. Note that the word ‘difference’ is a subtraction word, so that the 45 had to precede the minus sign and the number x had to follow it. No oth ...

6.4 Recursion Formulas
... Such formulas are known as explicit formulas. They can be used to calculate any term in a sequence without knowing the previous term. For example, the tenth term in the sequence determined by the formula tn = 2n + 3 is 2(10) + 3, or 23. It is sometimes more convenient to calculate a term in a sequen ...

Ambiguity
Ambiguity is a type of uncertainty of meaning in which several interpretations are plausible. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved according to a rule or process with a finite number of steps. (The ambi- part of the name reflects an idea of ""two"" as in two meanings.)The concept of ambiguity is generally contrasted with vagueness. In ambiguity, specific and distinct interpretations are permitted (although some may not be immediately apparent), whereas with information that is vague, it is difficult to form any interpretation at the desired level of specificity.Context may play a role in resolving ambiguity. For example, the same piece of information may be ambiguous in one context and unambiguous in another.
