Если перед скобками стоит знак "+", то знак в скобках (при раскрытии) не меняется

1) m + (-n) + p + (-k) = m - n + p - k

2) - x + (-y) + (-z) = -x - y - z

3) - ab + (-ac) + cd = - ab - ac + cd

4) -a + (-4c) + (-7) = -a - 4c - 7

5) -0,6a + (-11b) = 3 = -0,6a - 11b + 3

6) 9a + (-2b) + (-5c) = 9a - 2b - 5c

British love tea. They drink more tea than any other country in the world. They
drink 165 million cups a day – that is three cups of tea per person per day.
Tea drinking is not an old tradition in Britain. They made their first cup of tea
in the middle of the 17th century. They found that they liked it, that it made them
strong and happy. In the 19th century, tea became popular among working-class
people. And it is well-known that the Queen likes a nice cup of tea too.
Tea drinking has a longer history in China, where people have drunk tea for
thousands of years. Chinese tea is pale and delicate. But British tea has a rich
brown colour and a strong taste. Most people in Britain put milk and sugar in their
tea.
30 years ago most working people in Britain had their main meal in the middle
of the day. They called it “dinner”. Later in the day, people had a light meal at five
or six o’clock and they called it “tea”. And they had a cup of tea with their tea!
Today, most people have a light meal in the middle of the day – a sandwich and
an apple, which they eat in the office. We call this meal “lunch”. People eat their
main meal of the day in the evening, when they get home from work, and they call
this meal “supper”. “Dinner” nowadays is a formal evening meal for a special
occasion, where we dress up in smart clothes, and have nice food and wine and
candles!
