The app will take four numbers as input, then it will generate the fourth number from the three numbers using +(addition), - (subtraction), *(multiplication), /(division), !(factorial), ^ (exponentiation).

This app will help to improve one's mental analytical skills.Especially it will help kids/junior student to sharpen their mental arithmetic skills.

For example you can play with this app by entering the last 4 digits of Indian car number ( say 1 2 3 4)

*NO IN-APP PURCHASES AND ADS*
