Oops, that was a big blunder. Well, "not wrong" is the definition of correct, and on many math problems they say "which of the following statements makes the equation correct." And I don't know of any way you can make it correct.

C'mon, it was just an example. As I said, look at post #3.

I'll try it, but the Microsoft Small Basic Curriculum were downloaded directly from the Microsoft official website.

#171 Re: Help Me ! » Prove √5 is irrational... » 2013-01-22 01:55:38

The square root of 5 is an irrational number because the square root is ? x ? = _. So ? x ? = 5? Also, everything besides the square root of 2, 3, 5, 7, 8, 10, Pi, and lots of other numbers can be expressed as a fraction and a decimal. However, irrational numbers are never ending. For example, the square root of 5 goes on for 2.2360679774997896964091736687313... and it goes on forever.

2 = signs? According to Microsoft Small Basic Curriculum Lesson 1.4, (here is just an example:) you can do

If Clock.Day = 1 And Clock.Month = 1 Then
  TextWindow.WriteLine("Happy New Year!")
EndIf

'Ya see? Clock.Day = 1 and Month = 1. 1 equals sign. neutral

Say you have matchsticks in the form of the Roman Numerals X - X = X. You have to move one matchstick to make this sequence not wrong. X - X = X  (10 - 10 = 10.)

Hint: Not wrong.

I never recall posting a "newline character," I copied it right off my Microsoft Small Basic program.
