Solving the expression
we get -2.
Comparing the solution with the one given, you can find the errors.
Step-by-step explanation:
We need to simplify
and identify errors.
Since the steps are not shown, so we cannot identify errors but I can solve the expression and you can compare to find errors.
Simplifying:

Using algebraic rule: if one digit has positive (+) sign and other digit has negative (-) sign then we will perform subtraction. and after subtraction, the sign of bigger value will be the sign of result.
Using the rule and solving:
