It's possible to solve some multiplication problems in your head. But sometimes it can help to use other methods instead. These include using visual aids, such as an array or place counters, or by ...
Do you frequently feel that multiplication is difficult or time-consuming? Multiplication speed can significantly increase your confidence in arithmetic, whether you're doing problems in class or ...
After duplex numbers, let us learn multiplication by triplex numbers. As the name suggests, numbers like 111, 222, 333 are triplex numbers. The method is similar to that of multiplication by duplex ...
David Harvey receives funding from the Australian Research Council. Around 1956, the famous Soviet mathematician Andrey Kolmogorov conjectured that this is the best possible way to multiply two ...
Four thousand years ago, the Babylonians invented multiplication. Last month, mathematicians perfected it. On March 18, two researchers described the fastest method ever discovered for multiplying two ...
Hello children, in an earlier column we learned how to multiply the numbers from 12 to 20 by 9. Now we shall learn a general method to multiply any two-digit number (11 to 99) by 9. Step 2: Subtract ...
