(a2 * b) + c – d
1. a2
2. * b
3. + c
4. – d
a / A = x / X
| a | b | |
| — | = | — |
| A | B |
You’re trying to solve x. You have to cross-multiply. Be mindful of order of operations.
x * A = a * X x = a * X / A
Because I’m so nice, I coded up a very basic proportions calculator for you. Give it a try now!

OK. Let me show you how I do HTML5 for best speed and conformity. Check this:
To begin, the first thing you need to know about HTML files is that they contain only strings or text. They cannot be binary data like other kinds of files. Ironically, it’s binary anyway, but HTML data is required to be interpreted as text or string only.
So open your favorite string/text editor, such as Notepad or Notepad++, and create a new blank text file. You will be typing in the bare minimum text to structure a HTML file (the proper way anyway). (more…)
What I believe a game engine built on Qt/c++ needs in order for it to be accessible and successful. (more…)
If it ain’t broke, don’t fix it applies. Object-oriented programming has been implemented since the 1960s, so that’s 50 years of efficient practice. But could it be even more advanced? (more…)
If you can’t implement real 3D, then fake 2D 3D graphics might work. (more…)
