Question

12-(4) - 1 2 Please helppp!!! :)

Answer 1

Answer:

17

Step-by-step explanation:

Simplify:

$12\frac{1}{2} = \frac{25}{2}$  

$-4\frac{1}{2} = \frac{-9}{2}$

$\frac{25}{2} - (\frac{-9}{2} ) = \frac{25}{2} + \frac{9}{2} = \frac{34}{2} = 17$

When you have a subtraction sign next to a negative number, the negative number will turn positive since it's understood as -1 multiplied by the number when it's a negative number.
