Question

\([(−19,95)−45,75]+(4,95+5,75)\)

Answer 1

`[(-19,95)-45,75]+(4,95+5,75)`

`=-19,95-45,75+4,95+5,75`

`=(-19,95+4,95)-(45,75-5,75)`

`=-15-40=-55`

Answer 2

\(=-19,95-45,75+4,95+5,75\\ =\left(-19,95+4,95\right)+\left(-45,75+5,75\right)\\ =-15-40\\ =-55\)

Answer 3

\([(−19,95)−45,75]+(4,95+5,75)\)

\(= ( − 19 , 95 ) − 45 , 75 + 4 , 95 + 5 , 75\)

\(= ( − 19 , 95 + 4 , 95 ) + ( − 45 , 75 + 5 , 75 )\)

\(= − 15 − 40\)

\(= -55\)

Answer 4

-65,7+10,7=(-55)

Answer 5

[(−19,95)+(−45,75)]+(4,95+5,75)

=−19,95−45,75+4,95+5,75

=(−19,95+4,95)+(−47,75+7,75)

=−15+(−40)

=−55
