My father was born in 1910 and left school(as dux) at the age of 12 to work to support his family. His father was invalid with arthritis. I was doing some algebra when dad asked what I was doing. I explained what algebra was and he went away with this complex equation on some paper. A short while later he came in and asked if he had the right answers. To my amazement he had. I asked him how he did it and he said he rumbled some numbers in his head and the result seemed to fit. I often imagine what he might have become if he had had the chance of an education.
