Hi!
Solve this using PEMDAS.
Parentheses - addition
[tex] \frac{1}{2} - 3 (1\frac{1}{2})^{2} [/tex]
Exponents
[tex] \frac{1}{2} - 3 * 2\frac{1}{4} [/tex]
Multiplication
[tex] \frac{1}{2} - \frac{27}{4} [/tex]
Subtraction
[tex] -\frac{25}{4}[/tex]
The answer is [tex] -\frac{25}{4}[/tex] or [tex] -6\frac{1}{4}[/tex]
Hope this helps! :)
