This is called repeated addition. You add the same number lots of times. This can also be written as a multiplication calculation. There are five equal groups of two. The five represents the number of ...

All those long multiplication tables. Timed tests and “mad minutes” of worksheet problem-solving. Fluency drills. Somehow, getting kids to know their basic math facts continues to be at the heart of ...

A new proof about prime numbers illuminates the subtle relationship between addition and multiplication — and raises hopes for progress on the famous abc conjecture. One morning last November, the ...

A key part—though surely not the only part—of early-grades math is ensuring students get the basic arithmetic functions down and, beyond that, making sure they’re able to swiftly and automatically ...

Multiplication is calculating the sum of groups of the same size. There are lots of ways to build and describe multiplication problems. Using repeated addition, you can add equal groups together, one ...

The confusion (likely intentional) boiled down to a discrepancy between the math rules used in grade school and in high school. By Steven Strogatz Recently I wrote about a math equation that had ...

Researchers at MIT's Computer Science & Artificial Intelligence Lab (CSAIL) have open-sourced Multiply-ADDitioN-lESS (MADDNESS), an algorithm that speeds up machine learning using approximate matrix ...

Once the domain of esoteric scientific and business computing, floating point calculations are now practically everywhere. From video games to large language models and kin, it would seem that a ...

The many tributes pouring in honoring Ed Feulner—founder, trustee, and longest-serving president of the Heritage Foundation—are both fitting and deeply meaningful to those of us who wake up every day ...
