Level 7. Operators: The Math Toolkit

Operators are the symbols that do things with your values.

Operator	Meaning	Example	Result
`+`	Add	`3 + 4`	`7`
`-`	Subtract	`10 - 3`	`7`
`*`	Multiply	`5 * 2`	`10`
`/`	Divide	`10 / 3`	`3`
`%`	Remainder	`10 % 3`	`1`

These operators work on both integers and floats:

fun main() {
  let price = 5
  let quantity = 3
  let total = price * quantity
  println(total)
}

Operator	Meaning	Example	Result
`==`	Equal to?	`5 == 5`	`true`
`!=`	Not equal?	`5 != 3`	`true`
`>`	Greater than?	`10 > 5`	`true`
`<`	Less than?	`3 < 7`	`true`
`>=`	Greater or equal?	`5 >= 5`	`true`
`<=`	Less or equal?	`4 <= 3`	`false`

Operator	Meaning	Example
`&&`	AND — both must be true	`x > 0 && x < 100`
`\|\|`	OR — at least one must be true	`x == 0 \|\| x == 1`

🎯 Try it: Write a fun main() that computes how many seconds are in an hour (60 × 60).
