1. Addition +

2. Subtraction -

3. Division /

4. Multiplication *

5. Modulo operation %

6. Root square

Like a normal calculator, the online calculator should allow multiple digits and multiple operators in one calculation, such as (2*3)+10%2

You should design the interface and it does not have to be alike our normal calculator. The result can be shown in the same page where the digit buttons are or another page with a home button linking back to the digit button pad.
