"calculatorX2" is a SCIENTIFIC calculator "D.A.L." (Direct Algebraic Logic). Using the "D.A.L." the precedence of the mathematical operators is automatically taken into account by the calculator and it will therefore be possible to insert the various formulas, calculations, in the same order as they are written on the paper: the calculator will assign the right precedence to the various mathematical operators, brackets, functions, etc. Particularly suitable for both complex and simple calculations, suitable for all those who wish to have a "simple" and "accessible" interface. Input method: - D.A.L. (Direct Algebraic Logic) Types of calculator: - SCIENTIFIC (landscape orientation) Graphics of the calculator: - customizable: you can choose between 6 themes available (included in the app) App type: - UNIVERSAL APP

The factors of a number are all the integers that you can evenly divide into that number. The Greatest Common Factor (GCF) is the greatest integer that divides exactly into two or more numbers with no remainder. The Greatest Common Factor is used to simplify fractions. To simplify a fraction, you can divide the numerator and denominator of the fraction by the GCF of the numerator and denominator. Factors, the Greatest Common Factor, and simplifying fractions go hand-in-hand. Use this app to get the factors of a number, get the Greatest Common Factor of two or more numbers, and to simplify fractions.
