In general all integers, fractions, radicals and the numbers e and π are considered toīe exact numbers and all numbers written in floating point form (i.e. There can be any number of digits before and after the decimal point.)
( Floating point means that the number is written with a decimal point and This form is called the floating point form of these numbers. On the other hand, writing them like this: 0.667, 1.73, 2.7 and 3.14, is just anĪpproximation. When written in the form just shown, they are considered to be exact. Each of these numbers has a precise meaning and It put into simplest form by clicking the Simplify button.Įxact simplifications vs. You can type an unsimplified expression into the Algebra Coach’s listbox and get Just as you should do, the Algebra Coach program always returns its results in simplest form. Then we give an exhaustive list of possible simplifications ranging from the mostīasic that you will apply all the time to the most complex that you may never That can be applied to an expression: exact simplifications and floating point
In this section we first explain the two possible types of simplifications The person who has to look at your results will appreciate it! Similarly after you have finished working on an expression you Otherwise you are making your life harder than it has to be. Or combining it with some other expression) that expression should be in the 3.8 - Reference - Simplifying expressions 3.8 - Reference - Simplifying Expressions Before you start working on an expression (say factoring it, distributing it,
