I worked as an embedded developer for many years and I hid the fact that I struggled terribly in maths and had in fact had failed higher level courses several times. I've felt for the better part of three decades that my colleagues who were proficient in maths had superior capabilities and this has always been reflected in disparities in pay and promotion. I took early retirement and returned to uni to learn something new... After all these years I'm still struggling with maths but if there is one thing I've learned with near certainty is that the learning process all but demands working out all the maths with pen & paper. I think it's just part of the way the human brain works.
