I think that Jensen's position as the guy selling the proverbial shovels incentivizes him to take a lot of irresponsible positions (namely around safety) but imo he's fundamentally correct here.
As sometime who's memorized but also forgotten their timetables while still managing to go through Algebra I. I don't understand the importance for memorizing times tables (or any other tables for that matter).
Most people on a budget (i.e. the vast majority of people) are constantly using exact or approximate multiplication while shopping. And they are rarely whipping out their calculator for this purpose.
Why not just use the calculator app on your smart phone? That's what I do. (School made me all too aware of how easy it is for me to get the wrong answer when trying to do calculations mentally)
Depends on the calculation and context, it is definitely advisable to use tools for complex or high-risk situations, dividing the dinner bill by 2 or 3, that should not require a calculator or one of the thousands of bill splitting apps, perhaps it is a bit harder when you want divide bill by items, but not a high risk situation.
