The question is given below as
[tex]-|7|+|-18|-30[/tex]
Step 1: Apply the absolute value rule for
[tex]|a|=a,a\ge0[/tex]
That is,
[tex]|7|=7[/tex]
Step 2: Apply the absolute value rule also
[tex]|-a|=a[/tex]
That is,
[tex]|-18|=18[/tex]
Step 3: Therefore, By combining all the values, we will have
[tex]\begin{gathered} -|7|+|-18|-30 \\ =-7+18-30 \\ =-7-12 \\ =-19 \end{gathered}[/tex]
Hence,
The final answer is = -19
