See this link for a great example implementation in another app (WieBetaaltWat/WhoPaidWhat):

Having options of addition, substraction, multiplication etc when adding item so it will be easier to total the amount in the bill.

Yes good one need it

Google.com

Please add this also to split unequally.

This would be an excellent idea

sometimes I want to combine few values together and create just one evtry. I want the amount field to support simple expressions like "20+4.34+56".

You should add this feature to any number field for example when splitting unequally.
Would be nice to have this in the splitwise mobile app as itemised bill is not implemented there.

I suggest it works like this: the feature resolves an expression i.e. 1.11+0.51+0.70/2 when leaving the field and it replaces the field with the resulting amount 1.97. There is no need to see the expression afterwards or how I got there as its purely a calculator.

add easy to access calculator within app. Take receipt from online Walmart herb amazon etc accounts

It would be better if amount added can support mathematical calculations

Please add in calculator to count in separate debt. Especially in those situation that two persons carry different amount to add up.

been days still waiting for the App side calculator.... everyone uses app now.. high time to be added by now

This is such a basic feature that it should have come up in the initial idea forming! And now that you are aware of its lack since so long, what's stopping you from implementing it? It's a must have feature.

You are awesome, just add a handy calculator utility while adding expenses.cheers

It would be great to be able to add several numbers while using an option "Split by adjustment". Right now it takes into account only the first one, e.g. when I type "20.2+45.7" the bill is adjusted only by 20.2

Could you add an Calculator when you add new Entry. So you could give an input like: 5,99+3,99 and it will show 9,98

Hi Splitwise team,
Thanks all of you a lot to create a very useful application. This application can solve almost case of shared house. I am sharing this app to my friends and they said "Such a great app!!".

But sometimes I need to use a fomular in side the input field or a caculator right inside the app.

I think many other users want to have this feature in Splitwise. Please plan to implement it.

Best regards,
KhiemNS

to calculate splits n becomes easy
all expense managers have the feature

Please add calculator in this app.

It would be great to be able to add amounts with mathematical functions in the Amount field i.e. "2.09+3.49+1.89".
