You can't take 3 from 2, 2 is less than 3, so you look at the 4 in the 10s place. Now that's really 4-10s, so you make it 3-10s, regroup & you change a 10 to 10-1s & you add them to the 2 & get 12 & you take away 3, that's 9. (not a repeat from 1965)
Quick: What's 6 times 8? The answer, of course, is 48. But how you get to that conclusion depends on whether you went to school decades ago or you're a child in school today.
A few decades back, students were taught multiplication tables - 6 times 8 is 48 and so forth; rote memorization and formulas were the order of the day.
Today, schools are focusing more on getting children to better understand why answers are what they are, that there are multiple routes to the answers and how to apply that understanding.
