gồm 19 số 2 1 số 1 19 số 7 mà 1 số 8

\(815+\left[95+\left(-815\right)+\left(-45\right)\right]\)

\(=\left[815+\left(-815\right)\right]+\left[95+\left(-45\right)\right]\)

\(=0+50\)

\(=50\)

=50

78542556 x 1234547 = 96964476882132

a, S - 1258 = 3705

    S - 3425 = 1538

b, D + 2451 = 9142

When finding somewhere to escape from the hustle and bustle of life, my bedroom is always an ideal place. My bedroom is on the second floor. It is not exactly a large room but it is spacious enough to become my private world. It is a fully-furnished room with a single bed on the left and a wardrobe on the right corner. And there stands a wood table with a shelf that contains many interesting books and is decorated with lots of souvenirs and birthday gifts on the left corner. With two small windows on the two sides of the room, I use bright color tone for the wall to make my bedroom airier and warmer. My childhood memories is coupled with every corner of the room. In my deep thoughts, it is not only a place where greets me after strained long hours at work, brings me sweet dreams but also a friend that witnesses maturity in every step of my daily life. My bedroom- a small room but unintentionally becomes a vital piece in my whole life.
