SOLUTION
Write out the expression given.
[tex]\: 2+2-2+2+2+2-2-2[/tex]Follow PEMDAS in the other of operation
Add and subtract from left to right picking two numbers and one operation.
[tex]\begin{gathered} 2+2=4 \\ \text{Then} \\ =4-2+2+2+2-2-2 \end{gathered}[/tex]Then
[tex]\begin{gathered} 4-2=2 \\ so,\text{ we have } \\ 2+2+2+2-2-2 \end{gathered}[/tex]Add the next two numbers
[tex]\begin{gathered} 2+2=4 \\ \text{Then} \\ =4+2+2-2-2 \end{gathered}[/tex]Similarly, Add the next two numbers, we have
[tex]\begin{gathered} 4+2=6 \\ \text{Hence} \\ 6+2-2-2 \end{gathered}[/tex]Then, adding the next two numbers we have
[tex]\begin{gathered} 6+2=8 \\ \text{Then} \\ 8-2-2 \end{gathered}[/tex]Since the signed between the next two numbers is subtraction, we subtract the numbers to obtain
[tex]\begin{gathered} 8-2=6 \\ \text{Then} \\ 6-2=4 \end{gathered}[/tex]Therefore
2+2-2+2+2+2-2-2 = 4
Answer = 4
