NO BLACK pretty pink ,purple, blue, green, orange,yellow.

the area of a land in Telangana region in Andhra Pradesh State, India usually measures in Acres & Guntas. Guntas are fraction of acres.

solve equations like 3x+24=36
solve it like this -24 -24
3x/3 = 12/3
x = 4

Should be able to solve for variables. For example, 3x=9 to x=3. You should tell it what variable to solve for, so with V=3x/5-m, solve for x, you would get x=5/3V+m

Pop out Calculator
It would be really nice if when you open the chrome extension there was an option to have it pop out so you could move it around the desktop and not have to be showing a chrome browser. This was I could use it instead of my windows calculator for excel and other programs.

be able to put in equations like X+3=7

auto comma every 3 digits in a number

I would recommend you design a feature into the calculator where users could make it behave like one of the classic Hewlett Packard calculators. I find the reverse polish notation to be much faster for carrying out computations.

50%=0.25 ?
50+50*50%=5625 ?
50+50%=2550.25 ?

It would be nice to use negatives to do more complicated problems than having an error come up.....

option to pick decimal mark between comma and dot

solve equations to find thier roots...

different formula are used for algebra, geometry, arithmetic and if shown in calculator it will be great

It is very hard to find a calculator that will add subtract multiply and divide time. Am still looking for one.

Is good to have digit grouping in the calculator field.
E.g One million = 1,000,000

A calculator that does 6th grade math to 12th grade math

If you could implement an algebra system, for example, 1+a=2, that would be great!
thx

would be a very useful app to have on smartphones
