Question

12-(4) - 1
2

Please helppp!!! :)

Answer 1

17

Explanation:

Simplify:

`12(1)/(2) = (25)/(2)`

`-4(1)/(2) = (-9)/(2)`

`(25)/(2) - ((-9)/(2) ) = (25)/(2) + (9)/(2) = (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.
