Why when I include <cmath> I need to use the namespace std too?
To access a name (let's say the function pow()) that is declared inside the namespace std, you can access it in 2 ways: using the namespace access prefix std:: (i.e. std::pow()), or you can declare using namespace std. However as @Yksisarvinen mentioned, you should avoid the use of using namespace.

dev c++ - How to use fractions in C? - Stack Overflow
My code needs to be as simple as the one I am using now: c = a * b; printf("Answer = %f", c); return 0; You need to use float constants: The constants with suffix f have float type (1.0f, 5.12f). Without the suffix have double type (1.0, 5.12) Thank you! Do I need to use () for the fraction so that it does that calculation first?

Introduction to C++ - SpringerLink
The iostream class provides routines for input and output, while the cmath class implements elementary mathematical functions. The basic arithmetic operations +,-,∗,/ can be used without the inclusion of libraries. To output text and numbers, the command std::cout << "text \n" or std::cout << x is used, where \n causes a line break. The reading of values for a variable is done with std::cin ...
