![]() The second expression includes parentheses, so hopefully you will remember that the negative sign also gets squared. The first expression does not include parentheses so you would apply the exponent to the integer 3 first, then apply the negative sign. The key to remembering this is to follow the order of operations. Simplify the following numeric expression: \(\frac\).\) With that being said, always try to simplify fractions, and simplify your algebraic expressions in general, as it will usually ![]() ![]() You will end up carrying along an unnecessarily long term that can be greatly simplified. That could be a bigĭeal with you have a potential trig simplification like So then, if you had an initial expression that you did not simplify, you will then tag along unnecessary baggage for the operations that follow. Simplifying is like removing clutter, we all want to do that, right?Īlso, simplifying expressions will be a way of saving work, because often times you need get one result and then plug it into another expression, and then An expression may not tell you anything, but after simplifying, you can suddenly see everything clearly. Lots of the magic in Math is hidden in plain sight. For specialized structures, we can device a very complete way to simplify fractionsĪnd to simplify radicals, for example, which are among the most common elementary operations. It can be difficult to simplify a general expression.
