Code Challenge - jQuery User Input Calculator

Students will work in groups to create a calculator that accepts user input using jQuery event listeners and JavaScript functions, if/else or switch statements, and jQuery val methods.

The calculator should do the following:

1. Be object oriented.
2. the calculator should use jQuery selectors to get the input for 2 separate numbers and 1 operation: '+', '-', '*', '/'.
3. When the user clicks the equals button, the calculator should update the result h2 tag with the result. 1. If the user leaves a number field blank or inserts some input that is not a number then h2 with id="result" should instead print the error message: "Sorry, one of those is not a valid number!". 2. If the operation inserted is not one of the valid accepted operations then the error message should then read "Sorry, not a valid operation!"
