Multiplying and Mastering Equations With Three Digits on the Abacus | OwlcationTim Truzy is a rehabilitation counselor, educator, and former dispatcher from North Carolina. The abacus is an amazing tool for performing numerous types of arithmetic problems, including multiplication. In developing any skill, such as using the abacus, practice is required for mastery. This includes consideration of visual aspects of the abacus, auditory cues and responses, and application of the sense of touch. If you were to watch long time masters of the abacus at work, you may see those experts moving invisible beads with their fingers while going through the calculation process.
Using an Abacus/Multiplication
There are many ways to teach numbers and math to kids. Some can be fun and exciting and some can be just plain boring. The abacus is a calculating tool that may be as old as — BC. It has been used for centuries and is still widely used by merchants, traders, and clerks in Asia, Africa, and elsewhere. It also happens to be a great tool to teach numbers and arithmetic to kids.
Once you can add on an abacus, the next thing to learn is multiplication. Like addition, it follows pretty closely on the old pencil-and-paper method. But it's worth taking the time to look closely and see it step by step, because it's an important subroutine to use a programming term that will be useful in more complicated stuff. Write down a "0" for the initial value of the result. For each digit d j in the first number, from right to left: 1. When you finish, you'll have the product.

It's a useful learning device for the visually impaired, as well as for anyone who wants to learn the roots of the modern calculator. After learning the basics of counting on the abacus, you can quickly perform arithmetic like addition, subtraction, multiplication, and division. To use an abacus to add, first orient it by pushing 1 or 2 beads to the top of each row and 4 beads to the bottom of each row, which will set it back to zero. For example, the furthest column on the right should be the ones place, like , and the second farthest column on the right should be the tens place, like Then simply lower the beads, starting in the thousands place, to add to the second number, 5,
