What should people calculate in these creations?

The length The height

The quantity

The strengthThe speed The area

The width

The power The number The weight

Pentagon is the Ministry of the US Defence The length of one side is 280 m.What’s the total length of the walls?

280 x 5 = 1400 m.

The waterfall in South America is 1054 m. high.What’s the time of a parachutist free flight if the speed of a free flight is 9,8 m./sec. and he should open his parachute at the height of 300 m.?

(1054 – 300 ) : 9,8 = 70 sec

There is a flower show every 2 years in Grand-place(Brussels).How many flowers should be used if one side of the Grand-place is 24 m. and the other is 77 m., and there are 420 flowers put in each square meter ?

24 x 77 = 1840 420 x 1840 = 772800 (flowers)

The stature of Christ is made of marble, the volume of the used marble is 285 cube meters, the weight of one cube meter of marble is 2, 7 tons. How much does the stature weight?

2, 7 x 285 = 634,5 (tons)

Sophism is specially made mistake in solving a problem or calculating. To solve sophism means to find out a mistake.

Sophism 1

a² - b² = ( а – b ) ( a +b)

Let’s take a = b

Then a ( a – a) = ( a - a ) (a + a )Let’s simplify the equation - divide it by( a – a)We get a = a + aOr a = 2a

Where is the mistake?

George Byron (1788 – 1824 ) a famous English poet

“It is known that two multiplied by two is four. But I would be more pleased if it were five.”

2 x 2 = 5

Then 4=5Or 4 : 4 = 5 : 5Take out of brackets 4 and 54 ( 1: 1) = 5 ( 1 : 1)Divide both parts by (1: 1 )We get 4 = 5Or 2 x 2 = 5

Where is the mistake?

The more you know- the more you forget, The more you forget –the less we know, The less you know – the less you forget,The less you forget – the more you know.So, why study?

Where is the mistake ?

This is a beautiful flower of poppy

Every year a flower gives 3000 seeds

If all seeds could grow so next year there will be 3000 x 3000 = 9 000 000 plants

( the second year)

How many plants will there be in 5 years ?

9 000 000 x 3000 =27 000 000 000

The third year

(The fourth year)

27 000 000 000 x 3000 =81 000 000 000 000

81 000 000 000 000 x 3000 = 243 000 000 000 000 000The total area is 135 000 000 square kilometers It’s 2000 times smaller than the number of grown poppies

Every spring a lot of yellow dandelions decorate the streets and fields

Every flower gives 100 seeds

How many flowers could grow in 10 years?

How good are you at solving equations?

4x – 7y = 304x – 5 y = 90

5x + y = 6x = y - 10

4x + 5y =15x+ 7y =5

y – x = 9 7y – x =-3

Is English + Maths = Maths + English ?

English + Maths = a discussion about Maths

Maths + English = solving problems with the help of English

+ communicating with foreign people

So “ English + Maths “ is not equal to “ Maths + English”

Great!Terrific!Smashing!

It’s much more!
