There are no "following" data!
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
Don't write "the following" if you don't provide a list.
125 - x.

The rules for naming chemical elements and for chemical symbols are established by IUPAC; see this link.
You've done a fine job of it in your question. If you want to write it without those mathematical-looking number symbols, you could write "six hundred thirteen".
No, Eratosthenes did not write "Elements" about plane geometry. He is known for his work in fields such as geography and astronomy, particularly his calculation of the Earth's circumference. The "Elements" was a mathematical work by Euclid that focused on geometry.
Fourteen and two hundred fifty-one thousandths.
Because it is more simple to write one or two letters than a word and also these symbols are valid in all languages.
because it would suck to have to write out their full names everytime
To write an equation for a given problem, first identify the variables involved and their relationships. Then, use mathematical symbols and operations to represent these relationships in a concise and clear way.
The symbols that represent the elements were introduced by the Swedish chemist Jons Jakob Berzelius in the early 19th century. He used the first letter of the element's name in Latin to create the symbols, making it easier to write chemical formulas and equations.
square root of 0.2^-2=5
Chemicals symbols of elements are writed after the rules of IUPAC; see a list at the link below.
The abbreviations of the elements are called chemical symbols. They are typically one or two letters derived from the element's name in English or Latin.
