Question

a) A= 100 - 116 : 4

b) B= 100 - [ 116 - (13 - 5)²]

c) C= |- 65| + (- 42) + |65|

Answer 1

Answer 2

a) A= 100 - 116 : 4

=100-29

=71

b) B= 100 - [ 116 - (13 - 5)²]

=100-[116-8²]

=100-(116-64)

=100-52

=48

c) C= |- 65| + (- 42) + |65|

= 65+(-42)+65

= 88

Answer 3

a) A = 100 - 116 : 4

A = 100 - 29

A = 71

Vậy A = 71

b) B = 100 - [ 116 - ( 13 - 5 )² ]

B = 100 - [ 116 - 8² ]

B = 100 - [ 116 - 64 ]

B = 100 - 52

B = 48

Vậy B = 48

c) C = | - 65 | + ( - 42 ) + | 65 |

C = 65 + ( - 42 ) + 65

C = ( 65 + 65 ) + ( - 42 )

C = 130 + ( - 42 )

C = 130 - 42

C = 88
