<h3>Basic Math and String Operations</h3>
<h4>4 Tasks for this Practice Set:</h4>
<ol>
    <li>
        Write a script to add two numbers and output the sum to the console</li><li>
    Write a script that prompts for input, adds one to whatever number was input and outputs the sum to the console. Use the increment operator.  Assume that the input will be a number (no type-checking is required for this exercise).
    </li><li>
    Look up the Math object, and use one of its methods to do <i>something</i> to a number and output the result to the console (you pick: square it, round a decimal number up or down, do a trig function...whatever) Make sure the you comment your code or use console output to describe what you’re doing.
</li><li>
    Prompt for input and assign the result to a variable. Then, look up the String object, and use one of its properties to output the length of the string variable to the console.
    </li>
</ol>

JavaScript

// Insert your code for #1 here

var total = prompt("What is 5 + 5?") // this is my prompt

console.log("The varialbe 'total' is of type" + typeof total);
total = 10;
console.log("5 + 5 is " + 10);

// Insert your code for #2 here

var age = prompt("How old are you this year?") // this is my prompt
age = parseInt(age);
console.log("Now after parseInt() The varialbe 'age' is of type" + typeof age);

age = age + 1;

console.log("Next year you will be " + age);



// Insert your code for #3 here

var x = prompt("Enter number please", "");
var answer = Math.sqrt(x);

x = parseInt(x);// sqaring the root number of x.
console.log("the quare root "+ "is" + answer);


// Insert your code for #4 here

var n = prompt("What is the best hybrid car ever?");

var fullName = 'Chevy Volt';
fullName.length;
