In this video, you will learn how to solve a word problem using proportions. To do this we will identify our unknowns as well as our ratio of terms. We will then proceed to set up a proportion and ...

In this video playlist you will review problems you are likely to encounter when taking the act and SAT. FBI issues Iran surprise attack warning for California Odds of a ‘super El Nino’ growing, model ...

Abstract: This paper presents the hybridization of particle swarm optimization (PSO) with simplex search method (SM). SM is a deterministic method which is generally used for the local search and PSO ...

The original version of this story appeared in Quanta Magazine. In 1939, upon arriving late to his statistics course at UC Berkeley, George Dantzig—a first-year graduate student—copied two problems ...

For elementary students, math problem-solving often feels like a puzzle without all the pieces. They know there’s a solution somewhere, but they can’t quite see how it all fits together. Behind every ...

The leading approach to the simplex method, a widely used technique for balancing complex logistical constraints, can’t get any better. In 1939, upon arriving late to his statistics course at the ...

Standard computer implementations of Dantzig's simplex method for linear programming are based upon forming the inverse of the basic matrix and updating the inverse ...

For a long time, I purposely did not include lists like this on my site–lists of things like math word problem IEP goals. I refrained from putting math goals because struggling in math is usually ...

One effective method to improve the reasoning skills of LLMs is to employ supervised fine-tuning (SFT) with chain-of-thought (CoT) annotations. However, this approach has limitations in terms of ...

Have you been asked at work or school to create a problem statement and include a proposed solution, but you don’t know where to start? Continue reading for everything you need to know about problem ...
