You opt for beef with all the trimmings, safe in the knowledge that it’s a firm family favourite. Imagine you’re cooking a roast dinner for your family of four. They will also be essential for tackling some of the world’s most fundamental and complex issues, including climate change, as they help us allocate our planet’s often scarce and depleted resources in the most efficient ways possible.īut let’s first look at a simplified example to see what a dynamic resource allocation problem is and what makes it so difficult to solve. Whether you’re waiting for a taxi or a next-day delivery, the list of dynamic resource allocation problems and their everyday applications is “almost endless” according to Warren Powell, an engineer at Princeton University who has been investigating these problems since the 1980s.īut dynamic resource allocation problems are not just concerned with giving humans what they want, when they want it. ( Read about how a violent attack turned one man into a maths genius.) They crop up anywhere you find a limited resource that needs to be assigned in real time. Such problems are collectively known as dynamic resource allocation problems.
#HARDEST SIMPLE MATH PROBLEM HOW TO#
How to transform society’s view of time.This throws a mathematical spanner in the works, requiring these solutions to now take into account the changing and uncertain nature of the real world. But when an allocation made at one time affects subsequent allocations, the problem becomes dynamic, and the passing of time must be considered as part of the equation.
Over the last few decades, researchers have developed a range of pretty effective mathematical solutions that can allocate resources across a variety of industries and scenarios so they can attempt to keep up with the daily demands our lives place on them. We’re demanding creatures, expecting the world to deliver speedy solutions to our increasingly complex and diverse modern-day problems. It’s not easy to accurately predict what humans want and when they will want it. 1, 2019, 9:15 a.m.* This story is featured in BBC Future’s “Best of 2019” collection. A post meant to intentionally stew chaos on the internet? How groundbreaking. It's intentionally confusing, and will yield you either 1 or 16 respectively, depending on how you input it and what order you solve the equation.Īs it turns out, the way the equation is written intentionally confusing. But who am I to talk, I'm just a writer - let's hear what the experts have to say.īut the distinction between answers lies more in which notation you use to solve the equation, ÷ or /, than the difference between PEMDAS and BODMAS. As a millennial with pre-new math education, my conclusive answer is 1. So technically, both are the right answers! Boo, that's no fun. But if you were raised on the BODMAS (Opens in a new tab) method, then the order is Brackets, Orders, Division, Multiplication, Addition, Subtraction. If you use the PEMDAS (Opens in a new tab)method, the order of the equation is Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. The answer lies in the way you go about solving it, and that depends on where in the world you learned math. Pretty anticlimactic, huh? Here I was thinking that some dashing math majors would sweep in and put an end to the madness, but even they can't stop this viral fight now.Ī maths exam asked students to count calories in a woman's meal. What answer did you get? 1 or 16? The real answer may surprise you: no one can decide conclusively.

Pop quiz folks - can you solve this controversial post? I'm really gonna have to dig through my post-grad brain like SpongeBob's memory files, burnt to a crisp, and calculate this equation. You're all really gonna make me pull out my dusty TI-48 graphing calculator, huh. As someone who hasn't calculated anything more difficult than a restaurant tip in years, may I say that I can't believe we've made math trend on Twitter.
