About

RedoCalc

Features
Read full description

This is a calculator for people who only use it for simple calculations, such as adding up receipts or calculating the cost of a meal split between several people, but who are always worried about whether the input was correct. As it is a simple calculator, the only operations it can perform are - Four arithmetic operations (addition, subtraction, multiplication, division) - Percentage calculations (including calculations such as consumption tax using percentages) . The results are displayed as numbers with a digit symbol. There is no complicated exponential display. The calculation proceeds in the order of the keys you enter. There is no priority for multiplication or division. The formulas you enter are displayed in order in the upper area as a history. If you tap the white part, it will turn yellow and you will be able to modify that part. (You can modify not only numbers, but also arithmetic symbols such as + and ×.) If you tap “=”, the expressions from the first line to the last line will be recalculated. The result will be automatically copied, so you can switch to other apps and paste the value there.
