Does evaluate mean to find the value of a number?
Rather, of an expression.
What does it mean to evaluate an algebraic expression?
meaning to evaluate the variable in an expression. An algebraic expression is also a problem that contains no equals sign and you don't solve it, rather you simplify it.It means to solve something.
Why is it important to simplify a fraction?
It is important because you want small numbers, not big numbers. For example, would you rather have 100/100000 or 1/1000? 6/36 or 1/6?
Why is it important to write the answer in simplest form?
Because most people find it easier to work with fractions involving small numbers rather than equivalent fractions involving large numbers. They would rather use 1/6 than try to work with 261/1566.
Why is it better to solve quadratic equations in the complex number system rather than in the real number system?
It is not always better.Although quadratic equations always have solutions in the complex system, complex solutions might not always make any sense. In such circumstances, sticking to the real number system makes more sense that trying to evaluate an impossible solution in the complex field.
