Summation Calculation Using Pairing Method
题目要求计算一系列数字相加的和： \(23 + 20 + 19 + 22 + 18 + 21\) 首先我们可以将数字两两配对，这样可以更快的计算出结果： \(23 + 20 = 43\) \(19 + 22 = 41\) \(18 + 21 = 39\) 现在将它们加起来： \(43+ 41 + 39 = 123\) 所以这些数字加起来的和为123。
Solving a Math Question
To solve the question in the image, which asks for the sum of several numbers, simply add them together: 23 + 20 + 19 + 22 + 18 + 21 Now, add the numbers: 43 (23 + 20) + 41 (19 + 22) + 39 (18 + 21) Then, add these sums: 43 + 41 + 39 Which equals: 123 So, the answer to the question is 123.
