(17.85+15.17)+(-120)
help me
(17.85 + 15.17) + (-120)
= 17.85 + 15.17 + (-120)
= 17.(85 + 15) + (-120)
= 17.100 + (-120)
= 1700 + (-120)
= 1580
(17.85+15.17)+(-120)
=((17.(85+15))+(-120)
=17.100+(-120)
=1700+(-120)
=1580
(17.85+15.17) +(-120)
= (1445+255)-120
=1700-120

17 . 85 + 15 . 17 - 120
= 17 . ( 85 + 15 ) - 120
= 17 . 100 - 120
= 170 - 120
= 50
\(17.85+15.17-120\) = \(17.\left(85+15\right)-120=17.100-120=1700-120=1580\)
17.85+15.17-120
=17.(85+15)-120
=1700-120
=1580
\(17.85+15.17-120\) = ?
17 . 85 + 15 . 17 - 120
= 17 . ( 85 + 15 ) - 120
= 17 . 100 - 120
= 1700 - 120
= 1580
