Formula+ Calculator

Formula+ Calculator is fantastic at being a good calculator and will enable you to even save your frequently used formula for easier and faster calculation. Then all you have to do after that is insert the variable that changes. for example, let say you always calculate for area of a circle, which has a formula of π × r2, then you can use the editor to write 3.14*raduis^2, where radius is a variable that changes based on the area of the square. So on the editor page use the + button to add new variable.

List of saved formulas can be seen on the formula's section of the side drawer.

Formula+ Calculator can save and calculate complex formulas, as long as you know how to write then.

for example
percentage of x in y will be written as (x/y) * 100
Perimeter of a rectangle 2(l + b), where both "l" and "b" are variables
Quadratic Equation: x = −b ± √b²-4ac/2a

Just make sure that your respect rule of BODMAS (first BRACKET, OF, DIVISION, MULTIPLICATION, ADDITION and then SUBTRACTION)
