The efficiency of a device is the proportion of the energy supplied that is transferred in useful ways. The efficiency can be calculated as a decimal or a percentage, using the equations:
Jan 22, 2023 · That last sentence - "In mathematical reasoning, we only concern ourselves with truth rather than usefulness or efficiency" - is saying "usefulness and efficiency, while natural ideas, are not concepts used in mathematical reasoning". In other words, there can't be "rigorous" definitions for these qualities, because they aren't rigorous concepts!
May 17, 2021 · Today we speak with Tom Marker, a 14 year veteran sixth grade teacher from Ohio! Tom reached out to us to tackle the big struggle of trying to convince his students to avoid rushing to standard algorithms and instead value strategies that can be more meaningful outside the classroom. This is another Math Mentoring Moment episode where we talk with a member of the Math Moment Maker Community ...

Efficiency (statistics) In statistics, efficiency is a measure of quality of an estimator, of an experimental design, [1] or of a hypothesis testing procedure. [2] Essentially, a more efficient estimator needs fewer input data or observations than a less efficient one to achieve the Cramér–Rao bound. An efficient estimator is characterized ...
Apr 2, 2014 · Dowker (1992) The phrase 'number sense' is often used to mean conceptual fluency - understanding place value and the relationships between operations. Children need to be both procedurally and conceptually fluent - they need to know both how and why. Children who engage in a lot of practice without understanding what they are doing often forget ...
