Интересни формули за брзо пресметување напамет

Tutorial 1

  Use the formula ALL FROM 9 AND THE LAST FROM 10 to

    perform instant subtractions.
  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
Tutorial 2

  Using VERTICALLY AND CROSSWISE you do

    not need the multiplication tables beyond 5 X 5.

  Suppose you need 8 x 7

    8 is 2 below 10 and 7 is 3 below 10.

    Think of it like this:

  The answer is 56.

    The diagram below shows how you get it.

Tutorial 3

The easy way to add and subtract fractions.
Use VERTICALLY AND CROSSWISE

  to write the answer straight down!

Multiply crosswise and add to get the top of the answer:

  2 x 5 = 10 and 1 x 3 = 3. Then 10 + 3 = 13.

  The bottom of the fraction is just 3 x 5 = 15.

  You multiply the bottom number together.

Tutorial 4
A quick way to square numbers that end in 5 using

  the formula BY ONE MORE THAN THE ONE
  BEFORE.
75² = 5625 
75² means 75 x 75.

  The answer is in two parts: 56 and 25.

  The last part is always 25.

  The first part is the first number, 7, multiplied

  by the number "one more",
  which is 8:

  so 7 x 8 = 56

Similarly 85² = 7225 because 8 x 9 = 72.

	Имаше некој на нашите емисии(Тентов или некој сличен) кој ја објаснуваше оваа математика.Има фасцинатни работи за тоа еве нешто слично

	Зошто цифрите ги пишуваме онака како што ги пишуваме? Зошто еден е 1, а два е 2? Еве го одговорот:
