Интересни формули за брзо пресметување напамет
Use the formula ALL FROM 9 AND THE LAST FROM 10 to For example 1000 - 357 = 643 We simply take each figure in 357 from 9 and the last figure from 10. So the answer is 1000 - 357 = 643
Using VERTICALLY AND CROSSWISE you do Suppose you need 8 x 7 The answer is 56.
The easy way to add and subtract fractions. Use VERTICALLY AND CROSSWISE Multiply crosswise and add to get the top of the answer: A quick way to square numbers that end in 5 using 752 = 5625 75² means 75 x 75.
Similarly 852 = 7225 because 8 x 9 = 72. Edited by phenomenon - 23-Feb-2014 at 18:49 |
