Want facts and want them fast? Our Maths in a minute series explores key mathematical concepts in just a few words.
Generating electricity without the use of fossil fuels is not just an engineering and industrial challenge, it is also a huge mathematical challenge.
In this podcast author Coralie Colmez shares insights into her novel The irrational diary of Clara Valentine.
We talk to early career mathematicians who spent some of their summer holiday solving problems posed by industry — such as how to blend a perfect smoothie!
Don't like plantbased meat alternatives, but want to spare animals and the environment? There's hope on the horizon, aided by a good helping of maths.
Inverse problems are mathematical detective problems. They can help solve crimes, are used in medical imaging, and much more.
In my view, this entire article is unnecessary. Unless I'm wrong, you always solve within parenthesis first, then reset, so to speak, and go about the problem from the beginning, which in this case would place the mathematician back at the division portion. From there, you have a simple problem resembling 6/2*3=9. And you would solve it left to right to come up with the obvious answer that any online calculator I've tried comes up with; 9. Was this posted on April 1st as some elaborate joke? This is obviously 9, unless there are multiple versions of the rule of the order of operations.
