Basic Calculator Pro 2.1
A simple calculator that carries out thebasicoperations of arithmetic. The buttons of the calculator areclearylayed out, making entering calculations a simple task.As well as the four basic mathematics operations thecalculatorcan carry out square roots and powers. There are buttonsto includeyour previous answer in the next calculation as well astheconstant pi. Brackets can be used to enter morecomplexcalculations.The calculator follows the usual BODMAS rules for orderofoperations. There is no limit to the size of the calculationbeingentered and the top half of the screen can be scrolledhorizontallyto both review and edit the input. The cursor positioncan be setby touching the screen or using the buttons just belowthescreen.Although limited to basic operations, keeping thedisplayuncluttered and simple to use, this is a robust calculatorgivingaccurate results up to at least 10 significant figures.Please note that √25𝜋 will be interpreted as the square rootof25 then multiplied by pi. To find the square root of 25𝜋 youmustuse brackets i.e. √(25𝜋) also the calculator will apply a lefttoright order of calculations for operations of equalprecedence,including for powers, i.e a^b^c is equivelant to(a^b)^c
Basic Scientific Calculator 3.4
A free, straight forward and simple to usebasic scientific calculator that is both robust and reliable. Aswell as the basic mathematics operators the scientific functionsincluded are the trigonometric and hyperbolic functions, and theirinverses, and logarithms to base 10 and the natural logarithmfunction. A key to calculate factorials has also been included tofacilitate statistics calculations.The scientific calculator's display can be customized with thescreen and background colors being changeable. Each individualbutton's color can also be changed.The calculator operates with a precision of up to 15 significantfigures, although this can be reduced in the settings menu.The calculator will store the last 10 calculations, which arere-editable. Simply use the left and right keys at the top of thekeypad or scroll the top half of the screen and tap where you wishto place the cursor.The simple and straight forward design makes this scientificcalculator easy to operate but powerful enough to use for a varietyof applications.
