Primary school thought:
Xiao Ming has done 6 times more than Xiao Hong, 2 times more than Xiao Hong, and 22 more questions, which will not change, so Xiao Ming has done 22-6 times more, which is 16, so Xiao Hong is 16 = 18, and Xiao Jun is 16 *.
Junior high school thought:
Set an unknown number, Xiaoming X Road, Xiaohong Y Road and Xiaojun Z Road, depending on the meaning of the question.
X-y=6, z=2x, z-y=22, three ternary linear equations, simple and easy to solve.
x= 16,y= 10,z=32。 x+y+z=58
