Step-by-step explanation:

To evaluate this expression, let's first plug in the value of m into the expression.

1 + (- ) - (- )

To make this expression easier to solve, let's convert every value into a fraction with a a common denominator.

6/6 + (-4/6) - (-27/6)

Now we can solve.

When you add a negative number, it's the same thing as subtracting, so:

6/6 + (-4/6) can be written as: 6/6 -4/6, which is equal to 2/6

Now our expression is: 2/6 - (-27/6)

When you subtract a negative number, it's the same thing as adding that number, so:

2/6 - (-27/6) can be written as: 2/6 + 27/6

2/6 + 27/6 = 29/6

Since 29/6 is already in it's most simplified form, 29/6 is your answer.
