Subdividing [0, 1] into 10 equally spaced intervals of length 
gives the partition
![[0,1] = \left[0,\dfrac1{10}\right] \cup \left[\dfrac1{10},\dfrac2{10}\right] \cup \cdots \cup \left[\dfrac9{10},1\right]](https://tex.z-dn.net/?f=%5B0%2C1%5D%20%3D%20%5Cleft%5B0%2C%5Cdfrac1%7B10%7D%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac1%7B10%7D%2C%5Cdfrac2%7B10%7D%5Cright%5D%20%5Ccup%20%5Ccdots%20%5Ccup%20%5Cleft%5B%5Cdfrac9%7B10%7D%2C1%5Cright%5D)
