Question

Câu 13. (1,0 điểm) Thực hiện phép tính (tính hợp lí nếu có thể):

a) $99 - (74 - 129) \, : \, 5 + 2022^0$.

b) $(-35) + 127 + (-65) + 73$.

Answer 1

a. 99 - (-55) : 5 + \(2022^0\)

= 99 - (-11) + 1

= 110 +1

=111

b. = \(\left[\left(-35\right)+\left(-65\right)\right]+\left(127+73\right)\)

= -100 + 200

= 100

Answer 6

a)99 - (74 -129) : 5 + 2022 

                                              

                                              

 

Answer 7

a)99 - (74 -129) : 5 + 2022 

                                              

                                              

 

Answer 8

a)

= 99 - (55) : 5 + 1

= 99 - (-11) +1

=110 + 1 =111

b)

=(127 + 73) - (35 +65)

=200 - 100

=100                                              

                                              

 

Answer 9

a,99-(74-129):5+2022 

= 99-(-11)+1 

= 110+1

= 111

b,(-35)+127+(-65)+73

= (-35-65)+(127+73)

= 100+200

=300
