Life skills? You're actually preventing them from learning life skills. Math is not just about numbers. Knowing methods of how to get to an answer is an important life skill. Having given you the answer won't help you in life in the long run. You may score 100% on your assignments by just copying the answers from the back of the book but totally fail a test. Variables life changes and if you don't know methods on how to solve the problem and/or different problems, life will be tough for you.
You may have answers to many problems, but if you are unable to get to the answer, you will not be able to actually solve the problem. Many people have come up with the answers to solving school shootings but the problem exist because they are not able to execute the method(s) of getting there.
In conclusion, if you lack the knowledge to solve problems, when facing problems, you end giving the answers that you only know. Which many times it's wrong, resulting in you being wrong on many things. And repeating the wrong answer won't make it correct.
