Thank you. I am a 50 year old in New Zealand who stopped math after first year university (I went into health) and have rediscovered passion for it recently. More from a understanding what numbers and formula means as compared to solving equations to 'pass' exams. I really appreciate the clarity and simplicity without over simplifying of your videos.
