60,7+25,5-38,7

= 47,5

(-9,207)+3,8+(-1,5030)-2,8

= -9,71

60,7+25,5-38,7=47,5

(-9,207)+3,8+(-1,5030)-2,8=-9,71

5,075 - 7,775 = -2.7

(2,07+3,005)-(12,005-4,23)

=>2,07+3,005-12,005+4,23

=>(2,07+4,23)-(12,005+3,005)

2,07- 7,36+8.97 +1.03-7,64 = -2.93

`2,07 - 7,36 - (-8,97) + 1.03 - 7,64`

`= 2,07 - 7,36 + 776 + 3 - 7,64`

`= 776,07`
