Simplification of Expressions

 This simulation will help you learn how to simplify linear expressions. Consider an example: 2(4x+3x)+3x 8x+6x+3x 14x+3x 17x Note that You can use only one letter for variable notation. To designate multiplication, you can use either asterisk "∙" or, when multiplying by a variable, use concatenate operands (2∙x=2x ). You can use parentheses whenever you need. Note that "/" is not a fraction separator, it is only a divide sign, and its priority is equal to the priority of multiplication operator. 1/5∙3=(1/5)∙3, not (1/(5∙3) You can either use fractions in the form of "integral_part nominator/denominator" (e.g. 2 3/5), or conventional decimal fractions (e.g. 3.14). If your quotients are integers, the answer will be given in the form of a fraction (see above), otherwise, it will come in the form of a decimal fraction. In case the decimal fractions are used, the value of maximal deviation of the user's given root from the exact root is 1e-2. NB: Blank space is treated as a plus; consequently, you may not place spaces where they are not needed (e.g. before or after the character that is used to designate a variable). If an error message appears, make sure that the equation contains no extra spaces.
