When discussing brain development many questions arise and the first things that come into mind are:

Our Mission: Full Brain Development using Mental Arithmetic as a medium and Abacus as a tool. Now, can you imagine an elementary school student solving a problem that has bewildered your mind? And that too within in seconds and without any external devices, such as a calculator! It may be hard to fathom but it’s true.

If we tell you that these equations can be solved without the aid of external devices, you would probably find it humorous and think it is nearly impossible or solving the equation would be a lengthy process. Heading to retrieve a pen and paper? A calculator? Perhaps even resorting to searching for the answer on the internet? Before the concept is explained in great detail, ponder upon a few arithmetic questions: Just think of it as using a second sheet of paper - you'd use the two abaci just like one.An abacus is an ancient device used to make arithmetic calculations. Now, with 26 rods instead of 13, you can solve really complicated questions. A coupler is often helpful, to join the two abaci together.

The answer is simple - pick up more than one abacus.

Simply slide an extra bead into the tens column, and place a 6 in the one's column.įinally, you're probably wondering how to solve huge equations that have more than 4 digits.

Of course, many answers will involve adding a ten, for instance, if you're solving 7 plus 9. That is: if you're solving 715 plus 42, first move the 7 to the answer section of the abacus, then work out 15 plus 42 part of the problem. If you have one number with more digits than the other, move the extra digits into the third column before trying to solve the problem. Now, as you add the 5 and the 3 together, place the answer in the third column, then erase the tens digit from the first two columns. Right beside the 3, bring down the top bead, and slide up two bottom beads to make a 7. Move over a couple of columns, and slide up three bottom beads to indicate a 3. On the first column, slide down the top bead to stand for a 5, and bring up two bottom beads in the next column to represent our 2. The left third, the first 4 rods of the unit, will hold the first number. When solving a problem, let's divide the abacus into three parts. Thus, to indicate the number 7, slide up the first two bottom beads, and bring down the top bead in the same column. The bottom beads represent ones, and the top bead stands for five. To mark a number on the abacus, simply slide a bead next to the bar running the length of the unit. Nowadays, blind folks use it in much the same way as their sighted peers write out equations on a piece of paper. And now, it's more affordable than ever!ĭirections for the Math Abacus From Future Aids, The Braille Superstore.Īn abacus is a simple tool that people have used to solve math problems for hundreds of years. In summary, for a blind person, using the abacus is just like using a pen and paper to work something out. Yes, the abacus method of solving arithmetic problems is the standard for blind students, and training for the same is offered in schools in lieu of sighted kids working out problems long-hand on paper. And underneath the beads is a firm, stiff foam backing, which prevents beads from sliding around on their own. By 'recording' numbers on the abacus, then taking beads away or adding new ones, you're able to manipulate numbers independently and perform basic and complex calculations at the drop of a hat. Below this are four more beads, each of which represents a single 1 digit. At the top of each column is one single bead, which stands for 5. Using the abacus is perhaps far easier than it looks. Addition, subtraction, multiplication and division questions can all be performed on this nifty device - not to mention finding the square root of a number. Then, by simply taking away and adding beads to different columns, you can keep track of every step of the problem you're solving. This durable, plastic pocket-sized abacus has thirteen columns of beads which allow you to 'write down' your calculation. And of course, when you're still a kid in school, you're not supposed to use a calculator to do your math homework. Occasionally you won't want to disturb others around you by listening to your calculator out loud. Sometimes the batteries in your talking calculator will die suddenly.
