Why is it a good idea to check to see if your answer is reasonable?

If you dont check if your answer is reasonable other people may take it the wrong way and or it may always be wrong

Sometimes we can miss steps or incorrectly do a step. When we solve the equation we might think we have the right answer. If you double check your answer and input your answer into the equation, you can see if it is truly correct. Doing this makes sure that you won't get the question wrong
