运算器是电子计算机的重要运算器件,它相当于日常所用的算盘。我们用算盘解一个题,要对题目中的若干个数进行加、减、乘、除四种运算,必须根据题意,首先应当哪两个数进行运算,进行什么运算。接着还和哪个数进行什么运算,需要列出完整的解题计算式2。然后再一步一步地进行运算,得到我们需要的结果。用电子计算机解题也是一样,要求事先设计好计算程序,然后计算机根据计算程序,自动地并有条不紊地对数进行各种运 Calculator is an important computer computing device, which is equivalent to the daily use of the abacus. We use the abacus to solve a problem, we should add, subtract, multiply, and divide the four numbers of the numbers in the title. According to the questions, we must first calculate which two numbers should be used and what operations should be carried out. Then what is the number of calculations with the need to list the complete solution to the problem 2. Then go through the calculations step by step to get the result we need. Solving the problem with the computer is the same, requires the design of a good calculation program in advance, and then the computer according to the calculation program, automatically and methodically logarithmic various transport
