Question

\(\text{5 - (48 - 703 + 125 ) + (48 - 703 + 12) + 125}\)

Answer 1

ko biết dùng máy tính tính à

Answer 2

5 - ( 48 - 703 + 125 ) + ( 48 - 703 + 12 ) + 125

= 5 - ( - 503 ) + ( - 643 ) + 125

= 508 + ( - 643 ) + 125

= - 135 + 125

= - 10

Answer 3

   5 - ( 48 - 703 + 125 ) + ( 48 - 703 + 12 ) + 125
= 5 - 48 + 703 - 125 + 48 - 703 + 12 + 125
= 5 + ( 48 - 48 ) + ( 703 - 703 ) + 12 + ( 125 - 125 )
= 5 + 0 + 0 + 12 + 0 = 17

Answer 4

\(5-\left(48-703+125\right)+\left(48-703+12\right)+125\)

\(=5-48+703-125+48-703+12+125\)

\(=5+\left(-48+48\right)+\left(703-703\right)+\left(-125+125\right)+12\)

\(=5+12\)

\(=17\)

Answer 5

5-(48-703+125)+(48-703+12)+125

=5-48+703-125+48-703+12+125

=5-48+48+703-703-125+125

=5

Answer 6

5-(48-703+125)+(48-703+12)+125

=5-48+703-125+48-703+12 +125

=5-(48-48)-(703-703)-(125-125)+12

=5-0-0-0+12

=17

Answer 7

mình viết thiếu số 12

đáp án đúng là

5-48+48+703-703-125+125+12
