How to read formulas and write them into code?

Question

Mathematics

In general, they gave the task of writing programs using a formula, please tell me how to read them and how to describe it in code, I don’t need a ready-made solution, I just want to understand how to read and describe them, examples can be

Answer 1

I mean, how to read? From left to right, following the order of operations.
Here is the first formula r= ... - this means that the value of the variable r is calculated from the expression on the right. Variables p, g participate there, the values ​​of which are given to you.
There is a fraction, the numerator is the sum of p and g. The denominator is one plus the logarithm squared of the sum of the root of pg+p and g^2. Expand the brackets and get (p+g)/(1+log(...)*log(...))
Similarly, the second formula for y in terms of p,g,r and z (three of them are given to you, r is calculated in previous action).
Squaring - depends on the programming language. Or the sqr() function, or **2, or just write (expression)*(expression). lg() - call the built-in logarithm function. Again, it depends on the language, how exactly it is called for you. The square root is the sqrt() function.

Answer 2

As I understand it, the main problem is that the school didn’t properly explain how to write fractions in one line? Those. the equivalence of a horizontal slash and a forward slash (slash).

Maybe you still need to master the abstract concept of a mathematical function and how it relates to functions in programming languages.
