Mnemonic acronyms have been criticized for not developing a conceptual understanding of the order of operations, and not addressing student questions about its purpose or flexibility. [31] [32] Students learning the order of operations via mnemonic acronyms routinely make mistakes, [33] as do some pre-service teachers. [34]
For example, a sample question is "(16 × 5) - (12 ÷ 4)" (Answer: 77). The winner should not receive any assistance (e.g. using a calculator, asking another individual to calculate the answer for the winner) in answering the STQ. Enforcement of these rules is not very stringent, especially for small prizes.
An open-ended question is a question that cannot be answered with a "yes" or "no" response, or with a static response. Open-ended questions are phrased as a statement which requires a longer answer. They can be compared to closed-ended questions which demand a “yes”/“no” or short answer. [1]
Deductive reasoning improves with practice. Mathematical puzzles often involve BODMAS. BODMAS is an acronym which stands for Bracket, Of, Division, Multiplication, Addition and Subtraction. In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition and Subtraction) is the synonym of BODMAS.
A complex question, trick question, multiple question, fallacy of presupposition, or plurium interrogationum (Latin, 'of many questions') is a question that has a complex presupposition. The presupposition is a proposition that is presumed to be acceptable to the respondent when the question is asked.
The answer to the first question is 2 / 3 , as is shown correctly by the "simple" solutions. But the answer to the second question is now different: the conditional probability the car is behind door 1 or door 2 given the host has opened door 3 (the door on the right) is 1 / 2 .
Thus, complex hypotheses must predict data much better than do simple hypotheses before researchers reject the simple hypotheses. Recent advances employ information theory, a close cousin of likelihood, which uses Occam's razor in the same way. The choice of the "shortest tree" relative to a not-so-short tree under any optimality criterion ...
According to Grimes, the answer "yes" asserts a positive answer and the answer "no" asserts a negative answer, irrespective of the form of the question. [2] However, simple "yes" or "no" word sentence answers to yes–no questions can be ambiguous in English. For example, a "yes" response to the question "You didn't commit the crime?"
