The Math Equation That Tried to Stump the Internet: Education : Nigerialog.com - Nigeria's Premier Online Forum
Better still would be to teach everyone how to write unambiguous math expressions, and then all of this would go away. For those students destined to become software designers, writing code that can handle ambiguous expressions reliably whenever they arise, by all means exhume Aunt Sally from her crypt. For everyone else, let’s spend more time teaching our students the more beautiful, interesting and uplifting parts of mathematics. Our marvelous subject deserves better.Steven Strogatz is a professor of mathematics at Cornell and the author of “Infinite Powers: How Calculus Reveals the Secrets of the Universe.”
Just like the good professor (I call him good because he's trying to help dispel ambiguity here) said, teachers should give better and more applicable mathematical problems which can be a lot more useful in the real world. Convention uh... Here's how I'd do it:8÷2(2 2)=8÷2(4).... Brackets first, right? =8÷8=1That's how I'd do it...
Oga, you sure so?
Hehehehe ... 2(4)... I know it's the same as 2x4 but why change it... So I left it in brackets; and brackets go first...1... 1... That's my final answer...
Okay, Ogbeni let's look at it this way ...8÷2×4I think this is where the snag is.And if you look at the problem this way, suddenly you realize that you solve from left to right (per maths convention).
