![]() Then recreate one of the formulas in that space by dividing it to accommodate the rule. Īnd not if you’re willing to take it one formula at a time.Īll you have to do is take a wall in a Memory Palace. Not if you know how to use a Memory Palace. Seven: Commit the Rules and Anomalies To MemoryĪt first glance, the formulas that make up the Trachtenberg System seem like a TON to memorize. It’s called The Trachtenberg System of Basic Mathematics. Six: Learn All the Rules for One Kind of Operationīecause there are rules and anomalies along the way when learning the Trachtenberg system for multiplication, I created this table for you:Īlthough she doesn’t have the rules for addition, you’ll find those at the back of this book as well.Ĭutler also has another book with Rudolph McShane that teaches you the formulas for division, square roots and more. You have to do this any time the two digits you’re adding produce an answer greater than 10. You just need to place the zero in your equation and then carry over the remaining one. When you get to the part where you have to add 7+3, you’ll get a 10. Warning: There’s an anomaly in this approach that arises depending on the multiplicand. Add it to the equation.įinally, draw down the digit furthest to the left. Next, move to the next number to the left, which is six. We add this number together with its neighbor, which makes 5. ![]() In this style of equation, we start by drawing down the first number that has no neighbor. Remembering that a neighbor is always to the right of the number you are working with, here’s our equation: Let’s choose 623 to take one example and multiply it by 11. I suggest starting with a three-digit number at most. When learning the Trachtenberg system, it’s best to start small. Three: Choose a Number To Add or Multiply Then we’ll get into the variations of the rules. You also operate differently when performing addition. You have to know the right rule for the task.įor example, you operate a little bit differently when multiplying by 11 than you do when multiplying by 12. The hardest thing about the Trachtenberg System is that there’s more than one rule. 3 is a number and 2 is its neighbor, etc. Neighbor: the figure to the right of the number you’re working onįor example, in 67324, 4 has no neighbor because there is no number to its immediate right.Ģ is a number and 4 is its neighbor.Number: the specific digit you’re dealing with during the calculation. ![]() You would write the answer underneath the line: To express this equation using his system, you would have: ![]()
