Smooth Operator

Math Operators

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

  • + Addition
  • - Substraction
  • / 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 parens () to enforce priority:

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

And they are resulting in a value, as such they can be assigned to variables:

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

Instructions

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

You will declare a few variables:

  • lessSmooth that is just 1 less than smooth
  • semiSmooth that is the 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 !)
