So I’m looking for a tool that can tell me the total cost of things I buy. Like if I buy item A for 1,20€, item B for 5,60€ and item C for 10€, it tells me how much the things I’m buying cost, which would be 16,80€ in this case.
I tried looking it up, but apparently ddg is once again incapable of showing any relevant results.
If you read his title, he is actually looking for an online calculator. Supposedly, these offline ones are not up to date in mathematics.
