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.
