MindYourDecisions

MindYourDecisions is made by Presh Talwalkar, who studied mathematics and economics at Stanford University. Many of the puzzles he covers are suggested by viewers around the world.

The videos set a puzzle, invite the viewer to pause and try it, then work through the solution. Topics include geometry problems, logic puzzles, probability, exam questions and puzzles used in job interviews. The explanations are clear and patient, often showing more than one way to reach the answer. Many videos are short, while compilation videos gather several puzzles together. Viewers often suggest alternative methods in the comments, which shows that there is rarely only one way to solve a problem. The puzzles range from easy warm-ups to genuinely hard challenges.

Some highlights include:

A collection of seven logic puzzles, each one followed by a clear explanation of how to solve it.

An explanation of why multiplying two negative numbers gives a positive, a rule many people learn without knowing why.

A tricky multiple choice question about probability that seems to contradict itself, and how to think it through.

Engineering is about solving problems, and this channel is good practice. The puzzles build the habit of breaking a problem down, checking assumptions and finding a neat route to an answer. It suits students considering maths-heavy subjects at A level and degrees in engineering, computing or maths.
