Mathematical Expressions Homework

In order to learn this subject of programming well, you have to practice:

Popcorn hack 1: operations with variables

Popcorn hack 2: Make 2 variables x, and y. Compute 3 different operations and log it into the console with console.log();

Final Task: Build a system of functions that represent different mathematical expressions. Each of these functions will perform a different mathematical operation(ex: add, subtract). Make at least 5 of these different functions.

Popcorn Hack 1 (Progress Check)

Part 1:
In the javascript node below, make 2 variables, num1 set to 6 and num2 set to 3, then write the equation (num1 * num2) + (num1 / 2).

The output should be 21.

Part 2:
Next, keeping the same variables, add a new variable called total that is equal to the equation num1 / num2 + 2 ** 3, and this time make the equation

(total + 15) - numb1 ** 2 / 4

Write this code below:

%% javascript

// Part 1
let num1 = 6;
let num2 = 3;

console.log((num1 * num2) + (num1 / 2)); // Output: 21

// Part 2 - I flipped the operations as its still the same answer
let total = num1 / num2 + 2 ** 3;
console.log((total + 15) - num1 ** 2 / 4);


<IPython.core.display.Javascript object>

Popcorn Hack 2 (Progress check):

Create 2 variables x and y. With the output area below, provide 3 different operators used with the 2 variables
(ex: let sum = x + y;)
and fill in the output with a sentence that provides all three operators and their respective answer.

%% javascript

// Create variables
let x = 10;
let y = 5;

// Perform 3 different operations
let operation1 = x + y;   // addition
let operation2 = x - y;   // subtraction
let operation3 = x * y;   // multiplication

// Output sentence with all three results - Copilot helped me with this line
console.log(`When we add x and y we get ${operation1}, subtracting gives ${operation2}, and multiplying gives ${operation3}.`);


<IPython.core.display.Javascript object>

Final Task:

  1. Make 5 different functions, each with different operators/expressions:

  1. Be able to use the functions as well as document.getElementById to make the buttons output the result.

  2. Have fun! Mess around with different variables with different values, and maybe see if you can make any complex equations like the ones you’re learning in your math class. The end objective is for you to be able to use and understand math expressions.

Example function:

function add(a, b)
{
	return a + b;
}

Some ideas you can use:

Now that you have seen the example, you will start writing your custom functions in the html code block below:
Make sure to follow each comment on where to write your code, don't modify any existing code.

	// Function 5 Modulus

	}
