Let's simplify the given expression step-by-step.
The expression is:
[tex]\[
3 \cdot 4 - 8 \div 2
\][/tex]
1. First, perform the multiplication:
[tex]\[
3 \cdot 4 = 12
\][/tex]
2. Next, perform the division:
[tex]\[
8 \div 2 = 4
\][/tex]
3. Subtract the result of the division from the result of the multiplication:
[tex]\[
12 - 4 = 8
\][/tex]
So, the simplified value of the expression [tex]\(3 \cdot 4 - 8 \div 2\)[/tex] is:
[tex]\[
\boxed{8}
\][/tex]
