Elementwise operations on arrays
Arrays allow for efficient numerical manipulation of its elements. Let's explore element-wise mathematical operations by calculating price to earnings ratio using two arrays, prices_array and earnings_array from the previous exercise.
This price to earnings ratio, or PE ratio, is a financial indicator of the dollar amount an investor can expect to invest in a company in order to receive one dollar of that company’s earnings.
