+- C++ was originally designed as an extension of C

+  - There are programs that are valid C but not valid C++
+  - However, C++ supports every programming technique supported by C

+- A complex number is a number that can be expressed in the form `a+bi` where:
+  - `a` is the real part
+  - `b` is the imaginary part
+  - `i` is the imaginary unit defined as the square root of `-1`
+- We can define basic operations for two complex numbers `a=x+yi` and `b=u+vi` as:

+  - `a - b = (x + yi) - (u + vi) = (x - u) + (y - v)i`
