I think its time we push further on how we do the maths - I will always remember my son refusing to do all of a math worksheet because \"he already did them\" and when I pointed at 9x2 and said he hadn\'t done this one - he pointed at 6x3 and argued it was just reorganizing 3s. He won at that point...!   Sunil Singh: @mathgarden https://www.maa.org/external_archive/devlin/LockhartsLament.pdf
