8,196

Пошаговое объяснение:

1) -2,28 - 0,98 = -(2,28 + 0,98) = -3,26

2) -3,26 * (-2,6) = 3,26 * 2,6 = 8,476

3) 1,4 * (-0,2) = -(1,4 * 0,2) = -0,28

4) 8,476 + (-0,28) = 8,476 - 0,28 = 8,196

Fashion and clothes
A Sophie
My mum says I've loved clothes ever since I was
small. I had a great pair of red shoes when I was
little, and I never wanted to wear any others! So
maybe that's where it started. And I've always
refused to wear anything that I think is old-
fashioned!
Now, of course, I wear a uniform when I go to
school. It's not as bad as some people's - a dark
sweatshirt, and black trousers, or skirts for girls
if they want.
Outside school though, I wear really colourful
things, and I'm good at finding great clothes that
don't cost much-so all my friends want to come
shopping with me!

My friends are always amazed at the clothes I
wear. I make things myself, or I make changes to
the clothes I've got so that they look different - I
haven't got much money to spend! Anyway, the
good thing is that I know I'll never see someone
who's wearing exactly what I am!
I've had a lot of help from my mum, too-she
enjoys helping me find nice clothes on the
internet, and then she orders them for me. I'm
the only one at home that's so interested in
clothes, though. I've got two sisters, and they
buy clothes, but then get bored with them and
give them to me!

I've got a huge collection of T-shirts. Every time
I go somewhere, I buy a new one, especially if
it's got the name of the place on it.
Some have amazing designs on them. I don't
wear them very often as I'll never be able to
replace them! My favourites have a big tiger and
bird on. I got them on a city break to New York
last year. We went ice skating there, too, so I've
got a photo of myself skating-on a T-shirt! And
I've got some T-shirts I've decorated myself,
with coloured pens and things. My friends love
them, so I often have to make one for them, too!
