Ответ:

(254+26+1547):429+971

1) 254 + 26 + 1547 = 1827

2) 1827:429=4.26

3) 4.26+971=975.26.

(600−11552:38)+704−23

Сначала проведем деление в скобках:

11552

:

38

=

304

11552:38=304

Теперь вычтем из 600 результат деления:

600

304

=

296

600−304=296

Теперь прибавим к полученному результату 704 и вычтем 23:

296

+

704

23

=

977

296+704−23=977

(254+26+1547):429+971

Сначала сложим числа в скобках:

254

1547

=

1827

254+26+1547=1827

Теперь разделим полученную сумму на 429:

1827

:

429

=

4.26

1827:429=4.26 (округлим до двух знаков после запятой)

Теперь прибавим 971 к полученному результату:

4.26

+

971

=

975.26

4.26+971=975.26

37902−(8282+32273)

Сначала сложим числа в скобках:

8282+32273=40555

Теперь вычтем из 37 902 результат сложения:

:

25

=

1485

37125:25=1485

Теперь сложим результат деления и 515:

1485

+

515

=

1485+515=2000

Теперь вычтем из 10 000 полученный результат:

10000−2000=8000

Ответ: 8 000

AN NUSUAL HOME
In Sofia, Bulgaria, there is a very unusual family home. It is
five floors high and it's in the shape of a snaill! Its mouth is
a door and its eyes are windows. Its body and big round
shell are multi-coloured. The shell is full of little windows,
so light can get inside, and on top of it, there's a little
ladybird and a butterfly.
2
It is a very popular attraction for visitors to Sofia, but it is
also the home of one of the world's top architects. There
are no comers or straight lines in the building. There are
no bricks or concrete blocks. Every building material in
the house is light and friendly to the environment
3
The snail house has rooms just like a normal house. There
is a living room, bedrooms, a kitchen and a bathroom. It
has also got two garages. It has got old-fashioned
furniture and funny heaters to keep the house warm in
winter. The heaters are in the
shape of a frog, a ladybird
and a pumpkin. It is an
unusual home and a lot
of fun to live in
