The National Numeracy Network (NNN) is a multidisciplinary US-based organization that promotes numeracy, i.e., the ability to reason and to apply simple numerical concepts. [1] The organization sponsors an annual conference and its website provides a repository of resources for teaching numeracy.
[1] [2] Utility companies have used aluminum wire for electrical transmission in power grids since around the late 1800s to the early 1900s. It has cost and weight advantages over copper wires. Aluminum in power transmission and distribution applications is still the preferred wire material today. [3]

The concept of health numeracy is a component of the concept of health literacy. Health numeracy and health literacy can be thought of as the combination of skills needed for understanding risk and making good choices in health-related behavior. Health numeracy requires basic numeracy but also more advanced analytical and statistical skills.
2014: National Numeracy-commissioned research by Pro Bono Economics found that over the course of a year, the cost of low levels of numeracy is estimated to be around £20.2 billion which is roughly 1.3 per cent of GDP to the total UK economy. This cost is distributed between individuals (£8.8 billion), employers (£3.2 billion) and government ...
The National Assessment Program – Literacy and Numeracy (NAPLAN) is a series of tests focused on basic skills that are administered to Australian students in Years 3, 5, 7 and 9. These standardised tests assess students' reading, writing, language (spelling, grammar and punctuation) and numeracy and are administered by the Australian ...

Heating the hydroxides leads to formation of corundum. These materials are of central importance to the production of aluminium and are themselves extremely useful. Some mixed oxide phases are also very useful, such as spinel (MgAl 2 O 4), Na-β-alumina (NaAl 11 O 17), and tricalcium aluminate (Ca 3 Al 2 O 6, an important mineral phase in ...
