Hmm. This may not apply to all of you.

But don't you feel that you're been lied to about maths since young??

When you were in primary your teachers always told you that you must use the bigger number to subtract the smaller number.

For example: 6-10 is X but 10-6 is √

Then in secondary you find out that it is actually possible. You'd just end up with a negative number. And then your secondary teacher teaches you how to square root numbers. But you can only square root positive numbers.

For example: √9=3 but √-9 is maths error.

And now finally in A-levels. You find out that there is such a thing as √-1.

No wonder kids always feels like adults lie to them.

Haha. Just something I thought of today.
