Question

thực hiện các phép tính sau:

1, 5+22+37+2

2, 12-6+26-4

3, (2016+450)-2016

4, 364-(364-111)

5, 1972-(638+972)

 

Answer 1

1,

=66

2,

=28

3,

=2016+450-2016

=450

4, 

=360-360+111

=111

5,

=1972-638-972

=1972-972-638

=362

Answer 2

1) = 27 + 37 + 2

= 64 + 2 = 66

2) = 6 + 26 - 4 = 32 - 4 = 28

3) = (2016-2016)+450 = 450

4) =(364-364)+111 = 111

5) = (1972-972)-638 = 1000 - 638 = 362

Answer 3

1. 5 + 22 + 37 + 2

= 27 + 39

= 66

2. 12 - 6 + 26 - 4

= 6 + 22

= 28

3. (2016 + 450) - 2016

= 2016 + 450 - 2016

= 2016 - 2016 + 450

= 450

4. 364 - (364 - 111)

= 364 - 364 + 111

= 0 + 111

= 111

5. 1972 - (638 + 972)

= 1972 - 638 - 972

= 1972 - 972 - 638

= 1000 - 638 

= 362

Answer 4

1 = 27 + 37 + 2

= 64 + 2 = 66

2 = 6 + 26 - 4 = 32 - 4 = 28

3 = (2016-2016)+450 = 450

4 =(364-364)+111 = 111

5 = (1972-972)-638 = 1000 - 638 = 362

Chúc bạn học tốt!
