I want to add and subtract 20 rational numbers with process answers, 10 or less, and the poems about ideals should be modern.

Addition and subtraction of rational numbers, such as 1+ 1 = 2, 1- 1 = 0.

2-5×(2-3)

=2- 10+ 15

=7

When+is added in front of the bracket, the symbol inside remains unchanged, and when the number is added and subtracted in front of the bracket, the number inside becomes the original antonym.

. Untitled contemporary. Zhou Enlai

The great river song turned to the east, and the dense group helped the poor.

It takes ten years to break the wall, but it is difficult to worry about jumping into the sea.

19 17 In September, Zhou Enlai resolutely gave up the opportunity to study in Japan and decided to return to China in order to join the anti-imperialist and anti-feudal tide of the motherland. On the eve of Zhou Enlai's return to Japan, his old friend Zhang Hongchen and others sent him a farewell dinner and asked for a book as a souvenir. Zhou Enlai presented the poem with a brush.

Jumping into the sea is also a hero: jumping into the sea and throwing yourself in. Even if the ideal cannot be realized, it is a hero to die in the sea. Here, when studying in Japan, Chen Tianhua died in Omori Bay, Japan, to protest against the unreasonable expulsion of China students by the reactionary authorities and to arouse people's awareness.

The Ideal Sunshine of Ice Rain's Modern Poems

The ideal sunshine and water are as charming as a transparent body.

Start with a book and a casual look.

And a bizarre story, obscure and unknown reasons.

.

When the snow melts, the songs of birds in the sky will not stop.

The clear spring on the other side of the mountain is still a touch of youth.

It responds to the call of human mind with green water.

.

The ideal sunlight is reflected by water and water body.

Then the perception of handstand and graphics are connected like stories.

Another story continues, forming a person's body and world.

.

When the desert retreats, let the condensed clouds and unprovoked feelings drift away with the wind.

Let the fearless spirits of the earth play a sacred and lasting movement.

Let the acacia and enlightenment that go deep into fate point straight ahead.

.

The ideal sunshine is hidden in the blue and profound meaning of water.

It goes from far to near, from near to far.

Nonsense close to truth and illusion, and greed of dreams and conscience

Moved by forgotten or ignorant eyes again and again.

.

All those love words must also be brought by ideals.

About life's perception of sunlight, thoughts lurking in the soul

Like this spring, what should we do with the old saying?

Touching and reading with the hand of the soul can make that lasting emotion

Plain confusion passes through the dreamland of clouds, and then it suddenly becomes clear.

Ideal-dedicated to people with ideals all over the world.

* * * * Ideas * * * *

Some people say that ideals are utopian dreams.

Some people say that ideals are the deception of schemers.

Some people say: Ideal is mental madness.

Some people say that ideals are the shield and sword of losers.

I want to say: you have become a godless tramp.

I want to say: you have become a small wooden sail floating around.

I want to say: you have become a dissolute man.

I want to say: you have become a self-prisoner on the decadent stage.

Ideal: I need diligent people to keep irrigation.

Ideal: I need the test of the will of the frustrated.

Ideal: I need the fearless courage of the wearer.

Ideally, I need calm people to be patient.

God said: Ideal is everyone's crown.

God said: Ideal is everyone's file.

God said: Ideal is everyone's spaceship.

God said: the ideal is that whenever the sun and the moon are urged,

Write youth with blood.

Looking at the world trend,

Laugh and laugh at ancient and modern times.

There are stormy waves under your feet,

There are thousands of horses in the box.

Sing to the Buddha.

Teenagers have great ambitions,

It's done in one word, Kun.

Personal temples urge the sun and the moon,

Write youth with blood.

Looking at the world trend,

Laugh and laugh at ancient and modern times.

There are stormy waves under your feet,

There are thousands of horses in the box.

Sing to the Buddha.

Teenagers have great ambitions,

It's done in one word, Kun.

Come with the wind,

Walking in the rain,

See the truth first.

Look at the past three winters,

Thousands of flowers compete for beauty.

Birds in the sky are singing,

People all over the world rejoiced,

Everything is new.
