a * a, because Java has no square symbol.
Maths to Java
| Maths | Java |
|---|---|
| 2ab | 2 * a * b |
| a² | a * a |
| √x | Math.sqrt(x) |
Remember
| Write every * sign |
| Use Math methods for roots |
Maths writes two a b. Java gives an error. Why? Java needs every star. Two a b is two star a star b. A squared is a star a. Root x is Math dot sqrt. Remember. Write every star. Use Math for roots.
