Digital Divide With 1 Digit Numbers Use Mental Math To Find Quotients Mental math tricks are a collection of techniques, some based on algebraic manipulation and some on visualization, that aid in large arithmetic computations. they are useful for increasing the speed at which one can do these computations, but they also serve as a useful verification mechanism to help reduce computational errors (as results reached by multiple methods are less likely to be in. This is one of those times because when it comes to mental division, it turns out that it’s often helpful to multiply instead. like many mental math tricks before it, this one relies upon the fact that dividing by 10 (or 100, or any other power of 10) is easy—just move the decimal point one position to the left for each power of 10. Dividing multiples of 10,100,1000. when both the dividend and the divisor are multiples of 10 or 100 or 1000 we can divide them both by their common factor to simplify the problem. as the visual below shows 32 tens divided by 8 tens is the same as 32 ones divided by 8 ones. the answer is 4 in both cases. 8. using landmark numbers. landmark numbers, such as multiples of ten or a hundred, are familiar with students so they can be used as a mental math strategy when adding. for example 97 68. 97 is so close to 100. so you could add 3 to 97 and then subtract 3 from 68. 9. repeated doubling to multiply by 4 and 8.

I think this method of dividing is made by the uploader himself presh talwalkar. here's a summary of the method: starting with the digit 1 we draw 1 dot, for the digit 3 we draw 3 dots and so on we draw dots corresponding to each digit of the number we want to divide by. once we draw all the dots we are ready to connect all the dots. Mental calculation of more advanced divisions requires a different method. for example, when using the standard “ long division ” technique for mental calculation of 1829 ÷ 7.6543, we would need to calculate multiples of 7.6543, such as 7.6543 × 3 = 22.9629, and subtract each multiple from a remainder stored in our working memory.
