There are four seasons in a year in Viet Nam:The spring,the summer,the autumn and the winter.A season has a special weather type.

The spring make people feel the most comfortable.It's fine and dull,the wind is gentle that glide by my cheek.It's a season that is warmer than the winter and cooler than the summer.The trees is look full of vitality,many the green leafs,many young buds.Everybody send the best wishses to people that we love in the new year,at the time,having many festival is hold.But,this season is usually appear the drizzle,so the road is dirty and the air in our home is wet .

The summer make peole imagine the sea holidays.The temperature is the highest in year,evry morning when we get up the sun's come out and the middle day,the sun's shining (there's not a cloud in the sky) ,may be in the afternoon ;when the sun's just gone in,it raining cats and dogs.The weather in the season in the same kinky girl.So,people will escape it by the way:finding the tourist attraction is near the sea,see the while sand in a beach,fell the cool air under the heat wave.Howerver,many teriblle storm in this time.

The autamn is a romantic season.The yellow leaf is full of the road,everyone wear the simple clothes.Having couples are maried,they take a album wedding in the old street.But,in the morning,it have may foggy-will be difficult to see the road,it's dry-easy to fire.Sometimes,it had a heavy rain,sometimes it haven't had any rain for a fortnight.

The winter is very cold.In Viet Nam hasn't the snow ,the sleet or the ice but we fell the chilly .We have to wear many clothes to go out.When ever we also want to sleep,eat the hot food,not touch the water.So,we often busy in the end of the year to complete the worrk and come back home with our family.

Now,the weather is starting cool,we can live lazier.

﴾1/2﴿A= 1/2+1/2²+...+1/2²⁰¹³

A‐﴾1/2﴿A= ﴾1+ 1/2 + 1/2² + ... + 1/2²⁰¹² ﴿ ‐ ﴾ 1/2+1/2²+...+1/2²⁰¹³ ﴿

﴾1/2﴿A = 1 ‐ 1/2²⁰¹³ 

A= ﴾1‐ 1/2²⁰¹³ ﴿ : 1/2

A= 2 ‐ 1/2²⁰¹²

Xét số lượng của hai chữ số,nếu số lượng chữ số bằng nhau thì so sánh từ trái sang phải

X=(4x5):1 = 20

ta coi : tiền vốn : 100% tiền lãi : 20%

tổng số phần trăm tiền vốn và tiền lãi là :

    100% + 20% = 120%

tiền vốn người đó là :

     1800000 : 120 x 100 = 1500000 ( đồng )

             đáp số : 1500000 đồng
