Sci vs CloudLabs My First Calculator

一、Basic Description 1、This software is mainly used in the digital experiment of primary and middle schools, including physical, chemical and biological experiments. 2、To work properly, the software needs to be used with sensors and bluetooth transmitter modules (sensors are connected to bluetooth launch modules). The sensor data is sent to the receiving end of the iPad or iPhone via a connected bluetooth module. 3、The software operates on portable mobile devices such as iphone or ipad, which has bluetooth low power consumption of BLE 4.0. 4、The overall design of this software adopts the Qt5.12.0 technical framework and Objective-C mixing method. 二、Use Instructions 1、Start the App software,scan the QR code on the back of the wireless transmitter module, and establish the connection between the mobile terminal and the module. 2、There are three kinds of software in App: general, special, and data upload software. • General software The general software has a "one-to-several" function, which supports four-channel parallel data logging and data recording, calculating, and graph analysis, without shifting the software interface. • The special software The special software is a software package composed of multiple independent software interfaces. Each independent software interface corresponds to a scientific experiment or inquiry project. According to project requirements, special software presets the corresponding operation steps and sequence. The current list of specific items for specific software is as follows: • Data Upload The data stored in the module can be uploaded to the mobile terminal by the data upload software. For easy control, it is recommended that the software be installed on the device with a screen of 4.7 inches and above. Please ensure that the operating system version is iOS 11.0 or above.

In this simulation, you are tasked with building a calculator that can perform basic operations such as addition and subtraction. To prove that the calculator works correctly, you must participate as a jury in a marbles tournament by qualifying the participants. To do so, at the end of each encounter with the participants, you must choose, through mathematical operations, who is the winner and determine how many marbles each one will end up with. If your calculator isn't working properly, you must adjust it so that it performs the operations correctly.
