- Stop being idiots ====================
The central core of being an idiot is refusing to admit when you're wrong. One great way to be an idiot is to have people explain to you where you're wrong on something simple and straightforward, and instead of learning from it, you argue as if it's to be a point of opinion.
Math quizzes on Facebook, for example.
- The problem ==============
25÷5(2+3)
Is this a) 1 or b) 25
- The answer =============
It's fucking 25. B.
- Why ======
There is the concept of order of precedence in mathematics. The purpose of this quiz is to make it so that people who don't know this and refuse to admit it look like idiots. Welcome to the club.
Under order of precedence, some operations have to be done before others start, or else you get the wrong answer. After those are all settled, and only after, then you go left to right.
Parentheses go fucking first, idiots.
| Step | Why |
|---|---|
| 25 ÷ 5 (2 + 3) | How the problem starts |
| 25 ÷ 5 ( 2 + 3 ) ⇒ 25 ÷ 5 ( 5 ) | parentheses first |
| 25 ÷ 5 ( 5 ) ⇒ 25 ÷ 5 × 5 | implicit multiplication |
| 25 ÷ 5 × 5 ⇒ 5 × 5 | left to right |
| 5 × 5 ⇒ 25 | left to right |
25÷5(2+3) is 25/5×(2+3).
- The real problem ===================
When it's explained simply why people have this wrong, they get all "lol you dummy."
Here's Wolfram Fucking Alpha, the math engine that NASA uses. Assholes.
- What makes you idiots ========================
It's not being wrong.
It's refusing to admit being wrong.
