This is a calculator 1. you need to click the green arrow 2. you need to type what you need to do like multiplication addition subtraction or division 3. then it will ask you a the first number like for eg: 2 4. then it will ask you the second number like for eg: 4 5. then it will give you the answer 6 i said this as addition you can also try many more numbers have fun.
I thought why to use a google calculator when i could make my own.
