This Design Idea presents a method for fast integer multiplying and multiplying by fractions. What can you do when you lack access to a hardware multiplier or MAC (multiply/accumulate) function and ...

This summer, battle lines were drawn over a simple math problem: 8 ÷ 2(2 + 2) = ? If you divide 8 by 2 first, you get 16, but if you multiply 2 by (2 + 2) first, you get 1. So, which answer is right?

The method to divide fractions is to keep the first fraction the same, turn the divide sign into a multiply and turn the second fraction upside down. This is known as multiplying by the reciprocal.

Fractions, often perceived as daunting, become manageable with the right approach. Addition and subtraction require finding a common denominator, while multiplication involves directly multiplying ...

Algorithms have been used throughout the world’s civilizations to perform fundamental operations for thousands of years. However, discovering algorithms is highly challenging. Matrix multiplication is ...
