The change also ensured the quarter dollar (which is valued 2.5 times the dime) weighed 2.5 times the dime (6.25g), and the half dollar (twice the value of the quarter dollar) weighed twice what the quarter dollar weighed (12.5g). In this way, a specific weight of these coins, no matter the mixture of denominations, would always be worth the same.
[8] A 1796 half dime. The half dime was originally struck from 1794 until 1805, though none were dated 1798, 1799, or 1804. [9] By 1804, silver US coins were heavily exported, as they could be exchanged at par in the West Indies with heavier Spanish coins, which were then imported as bullion and deposited at the Mint for melting and restriking.
The Quarterly Journal of Pure and Applied Mathematics was a mathematics journal that first appeared as such in 1855, but as the continuation of The Cambridge Mathematical Journal that had been launched in 1836 and had run in four volumes before changing its title to The Cambridge and Dublin Mathematical Journal for a further nine volumes (these latter volumes carried dual numbering).

The Common Core State Standards Initiative, also known as simply Common Core, was an American, multi-state educational initiative begun in 2010 with the goal of increasing consistency across state standards, or what K–12 students throughout the United States should know in English language arts and mathematics at the conclusion of each school grade.
Until 2019, there were three STEPs: STEP 1, STEP 2 and STEP 3. Since the academic year 2019/20, STEP 1 has been phased out. There was no STEP 1 set in 2020 due to the COVID-19 pandemic, and it was later announced that from 2021, STEP 1 would no longer be set, with only STEP 2 and STEP 3 being available. [5] The last STEP 1 was held in 2019.
In mathematics, a module is a generalization of the notion of vector space in which the field of scalars is replaced by a (not necessarily commutative) ring. The concept of a module also generalizes the notion of an abelian group, since the abelian groups are exactly the modules over the ring of integers. [1]
