Is there a quick way to divide numbers?
In: Mathematics
Divide each number separately and add back in.
353 / 2
Divide 300 / 2 = 150
Divide 50 / 2= 25
Divide 3 / 2 = 1.5
Add back up. 176.5
Alternatively, break the number I tho the largest chunks you know.
350/2 = 175.
You’re left with 3/2 = 1.5
Add them back up to get 176.5
This is actually the base of common core math. It’s about seeing numbers as relative and learning ways to manipulate them to make math easier. The problem is the teachers who taught common core didn’t understand the why of it.
