How to multiply 2 digit numbers using Singaporean Math
Good morning everyone! I am here today to teach you guys how to Multiply 2 digit numbers using Singaporean Math. This Singaporean method is an easier alternative in multiplying 2 digit numbers if you are too lazy to compute the method we all know. This manner of computing is taught to kids, as young as 4 together with their reading and writing. To do this, first, we need to have 2, two digit numbers. Let us take 12 and 13 as examples. We first take the multiplicand of the equation and represent its digits with sticks and place them separately as is. (illustrate front of the class.)
After doing so, we represent the multiplier’s digits as sticks too. After which, we will place the number from the ones place at the bottom of the diagram of the multiplicand and the ten’s representation at the top of the diagram. Basically, we have formed a square. To get the results, we count the interactions made by the sticks in the corners of the square. The lower right part will be the digit for the ones; the middle number would be represented by the interactions from the upper right corner and the lower left corner and the highest place value would come from the upper left corner. As we can see, we have 6 for our ones place, 5 for our tens place and 1 for our hundreds place. If we compute this from our calculators, we would also get the same results.
If ever we encounter double digit results from the interactions, we do what we have been taught in the traditional math. We carry these numbers to the next place value.
For example we take 33 multiplied to 14. Notice that the ones place will have 12 interactions. The number from the tens place, 1, will be carried over the next number of interactions. For the tens place, 15 interactions were counted, plus one, we get 16. Again, we will place 6 to the tens place and carry one to the hundred’s place. There are 3 interactions in the upper left
