calculadora | A simple calculator built with HTML CSS and JS | Apps library

I made a calculator in Java but I want to show the arithmetic operators in the screen. I dont know why this dont happen, I think it is because the method calcular overwrite immediatly, I dont know. To make the reset in screen I used a boolean variable called reset.

I made comments to clarify the code. Maybe the error is in the class Operadores or in the method Calcular.

PD: Im relatively new in Java, so any suggestion to my code is well received.

Greetings :)

I'm writing a simple client-server calculator with rpcgen and am having a compilation error. Here's the .x file (calculadora.x):

Basically i want to make a program in python that, given a list of words and a list of letters, it will print out a list with only the words that don't contain any letter in the list of letters.

I have a tableWidget on my Pyqt5 app on Python. The issue is that I am trying to connect to the calculadora function when a specific cell changes, so i have two questions:

• What is the difference between .cellChanged and itemChanged.?

-Right now i am using this:

I am doing a (very basic) calculator in php and I want that the inputs with the numbers keep them. As far as i know there is any way to have an input with text inside already. Also, placeholder is NOT what i need because i want that the person, if he mistakes, could easily erase one or two numbers instead of re-writting everything. And (if possible) i would like to know if i can use php variables in it

Here is my code:

as it says in the title, I am trying to make a calculator in which the user enters the numbers and it does the most basic operations. The problem is that the client part does not work when I run it, the screen remains blank, I have checked the routes with the libraries and they are perfectly fine so I don't know where the fault lies, here I attach the code for both the client and the server .

server code:

I have a menu with two links, it should take me to those two components, but they are not showing at all. The routing is very basic, two components and an empty route, i have been following the tutorials i´ve seen, your help and patience will be very appreciated.

I'm currently trying to solve a school work I was assigned with, but I'm struggling to solve a pretty simple issue.

I'm trying to keep a simple html and js calculator and a json table in the same line but I haven't managed to do it yet and I've been trying for a while. I'm leaving only the html code below since the problem is there and not in the scripts. Help appreciated! PS. Using bootstrap

I'm having trouble creating buttons in tkinter, I've tried doing it in different ways, but I haven't reached the solution.

It turns out that one of the requirements that they have made me when making this calculator is to create three text boxes and eleven buttons, so when I create the positioning of the boxes and I want to place the buttons they do nothing, if I try to tell them to position in column 3, row 4 is not positioned.

This is the code, if you see something wrong that I have not been able to see and that is the cause of such an error, I would appreciate it
