Math Operators

In JavaScript, operators are symbols that perform operations on variables and values. Let's delve into the most common types of operators you'll encounter.

There are other operators other than assignment, for now let's focus on the one you probably already know:

• + Addition
• - Subtraction
• / Division
• * Multiplication

Those operators are used the same way we would write them in math:

console.log(5 + 7); // -> 12
console.log(5 * 5); // -> 25
console.log(7 - 5); // -> 2
console.log(9 / 3); // -> 3

Operators are evaluated using classic priority:

console.log(1 + 5 * 10); // -> 51

you can use parentheses () to enforce priority:

console.log((1 + 5) * 10); // -> 60

And they result in a value, so they can be assigned to variables:

let halfMyAge = 33 / 2;
let twiceMyAge = 33 * 2;

Prompt example:

"Can you provide step-by-step examples of basic math operations in JavaScript?"

Placeholders

JavaScript allows you to include expressions within strings using template literals. This is done using backticks (`) and the ${} syntax to include expressions.

Example

console.log(`5 + 10 = ${5 + 10} = 15`); // -> 5 + 10 = 15 = 15

Note that it only works using: the ` backtick, not the " or ' quotes.

Prompt example:

"Can you provide a step-by-step guide on how to use template literals to create a string that includes variable values in JavaScript?"

Instructions

Task 1:

Your code must use the given variable smooth as our initial value

When in doubt, always test your code with console.log() and the Run button.
But, when the platform gives you an already existing variable to manipulate, like the smooth variable here, if you want to use/display it, you have to do so with the submit button.
You'll then see the result in the code editor console output, as this variable is not available in Run button mode, but only in Submit button mode.

console.log("smooth = ", smooth);
let lessSmooth = smooth - 5;
console.log("lessSmooth = ", lessSmooth);

You will declare a few variables:

• lessSmooth that is just 1 less than smooth
• semiSmooth that is half the amount of smooth (it's still pretty smooth)
• plus11 that is smooth plus 11
• ultraSmooth that is the square of smooth (now that's smooth !)

Task 2:

We will provide a variable name and age. They will be pre-declared by us.

Declare your robot's presentation variable of the string:

Hello, my name is name and I'm age years old But use placeholders to build the string you will put inside the presentation.
Put the values of the provided variables age and name inside those placeholders.
