Scientific calculator,calculator online,calculator,online calculator,MR: Memory read key. Indicates that the displayed value is replaced by the value in the memory. After pressing this key, the numbers stored in "M+" or "M-" can be displayed or calculated at the same time, and the numbers are still stored in the memory and are valid until the "MC" key is pressed. MR recalls the memory contents and reads the stored data. If three groups of numbers are not consecutively added together, use this "MR" key. For example: when inputting "3+2", press the "M+" key, then when inputting "6+7", press the "M+" key, when inputting "8+9" again, press the "M+" key, and then press " MR", the sum of the three sets of numbers "35" comes out.The calculator is a handheld machine that can perform mathematical operations. It has integrated circuit chips, but its structure is simple, which is much simpler than that of modern computers. It can be said that it is the first generation of electronic computers (computers), and its functions are also weak, but it is more convenient and Inexpensive, can be widely used in business transactions, is one of the necessary office supplies.Scientific calculator is a scientific calculator with compact size and very simple functions. It supports multi-line input, and users can input complete calculation formulas for operation. It can be used for scientific computing, including conversion of different base numbers. Its interface design is very user-friendly, using almost the same interface as the physical scientific calculator, helping users to quickly enter the calculation.
