The abacus is a computing device on which arithmetic calculations are performed by sliding counters (beads, pebbles, or flat discs) along rods, wires or lines. The instrument may have originated in ...

When good mathematicians are stuck on a problem, they see if they can simplify it. In long multiplication we break the sum down into parts that we can easily answer and then add the parts together ...

An abacus is an ancient tool used for counting, consisting of a framed set with rods on which balls or beads are moved. The abacus has been in existence in China since the second century BCE, although ...

The Russian abacus (tchoty) is held so that counters move crosswise. It has no crossbar, and all counters in one row have the same value. Most rods have ten counters. An occasional row has fewer, to ...

In addition to calculating the basic functions of addition, subtraction, multiplication, and division, the abacus can calculate roots up to the cubic degree. Abacus is also an academic accounting ...

Researchers have developed an ultrasensitive, human-like robotic ‘finger’ capable of safely performing routine physical examinations like a medical doctor would. They say the ‘robodoctor ...

What if you kept nibbling? What if you started biting? Would it be anatomically and psychologically possible to bite your own finger off? What about someone else’s finger? It’s a question that ...

Loved for its caviar-like pulp and jewel-tone colours as much as for its tart juice, finger lime is an ideal citrus. Here are 15 recipes where the native Australian ingredient is the hero. Want 20% ...

To test the finger's medical chops, they mounted it on a robotic arm and watched as it identified three lumps embedded in a large silicone sheet, pressing on them like a doctor would.
