You are required to implement a calculator Android activities. The way the Calculator works is similar to the Windows calculator. The user types the first number using the keypad buttons of the calculator, presses an operation, then the user types the second number using the keypad buttons of the calculator (no keyboard input required). If it clicks the ‘=’ it performs the operation. If it clicks an operation button, it performs the previous calculation, shows the result of the first calculation and waits for the second operand of the new operation. When the user presses delete, it deletes the last number that was pressed to create a number (e.g., if the number is 123, after pressing delete, the number now is 12).

Requirements:

• You are required to implement four operations (+, -, *, /)

• The numbers must be input by using the buttons

• Check for divisions by 0. An indication that an error has happened should appear if the user tries to divide by 0. If so, the memory of the calculator is cleared (it performs the same operation as if the user has clicked the Clear button).
