4-step approach to problem solving by George Polya

Later mathematicians use the word "SPAR" to represent the 4 steps --- See, Plan, Act and Reflect

P5, P6 TFNPTT

Well-intended advice for tackling TFNPTT questions (True, False, Not Possible to Tell)

Well-intended Advice:

● For True statements, circle the facts from your observation or calculation to justify

● For False statements, circle the non-facts and 

   ○ State what the facts ought to be or

   ○ Cite numerical inconsistencies that doomed the statement to falsehood. (eg. when certain numbers have to be odd, or say multiples of 3 etc, as dictated by certain ratios as stated in the question, and yet are inconsistent)

● For Not Possible to Tell (NPTT) statements, circle the ambiguous word/clause and cite other possibilities to satisfy the claim of the statement.* 

*Usually statements that are deemed NPTT can have more than one possibility. It is  flagged out as "not possible to tell" as there is not enough information to confirm the statement to be True or False.

The 7 Deadly Sins of Mathematics

Math Animations on Instagram: "Indeterminate forms are expressions that arise when evaluating limits but do not have a clear or predictable value on their own. They often occur in calculus, especially when dealing with functions that approach infinity, zero, or both. An indeterminate form signals that the situation is more complex than it appears and that standard arithmetic rules cannot be directly applied. For example, when both the numerator and the denominator of a fraction approach zero, the result is not automatically zero or any specific value. Instead, we say the expression takes the indeterminate form „zero over zero," and further analysis, such as using algebraic simplification or L'Hôpital's Rule, is needed to find the actual limit. Other common indeterminate forms include expressions like infinity divided by infinity, zero times infinity, or one raised to the power of infinity. These forms are called "indeterminate" because they can lead to many different outcomes dependin instagram.com
