Question above is pretty blunt but was doing a study for a college course and came across that stat. How is that possible? My high school sucked but I was well equipped even with that sub standard level of education for college. Obviously income is a thing but to think 1 out of 5 American adults is categorized as illiterate is…astounding. Now poor media literacy I get, but not this. Edit: this was from a department of education report from 2022. Just incase people are curious where that comes from. It does also specify as literate in English so maybe not as grim as I thought.
Does she understand the concept of multiplication though? That’s ultimately the important part.
Learning rote things like multiplication tables seems kinda silly in a world where Google can just do the math for you. But the important thing is to be able to recognize when multiplication is useful.
There are still plenty of instances where doing arithmetic quickly in your head is useful (figuring out a tip at the cash register, for example) that memorizing it can have advantages.
I agree that mental math is useful, but in scenarios like that, times tables aren’t really useful since the tables are rotely memorized and rarely does a bill fall nicely into a times table.
Better to learn a technique like “move the decimal place left one position and double that number to get 20%”.
But realistically, with a phone in your pocket, it’s not much more effort to pull it out and use the calculator.
