Scientific Calculator

Scientific calculator provides nodes in wanted count to make results available in seperate nodes. To add nodes, press enter and to remove them, click the trash icon. All nodes make calculations automatically and you can use results in lower nodes by naming them in "var" column. The only rule is that a name must be a single letter or a letter with sub indicator. Here is an example: Variable a_c looks different in var column, keep in mind that the underscore indicates subtext in "calculation" column ( a_c ), while it looks as what it is at "var" column. The only letter that cannot be used is "e" which represents Euler's number.
