Given the expression:
[tex](4.5+7.6)-8+2.5[/tex]first we do the operation inside the parenthesis to get the following:
[tex]\begin{gathered} (4.5+7.6)-8+2.5=12.1-8+2.5 \\ \end{gathered}[/tex]Now we can add and substract the resulting expression:
[tex]12.1-8+2.5=14.6-8=6.6[/tex]therefore, the result is 6.6
