1 You were always taught that you cannot take the square root of a negative number, so an equation like x2 = −9 has no solution. Ah, but you can “imagine” the solution to be x=3(−1) because when you square x you get x2 = −9. Today imaginary numbers are an important...

So -x means a bad hair week. Notice how negative numbers “keep track of the sign”: we can throw(−1)47into a calculator without having to count (”Week 1 is good, week 2 is bad… week 3 is good…“). Things that flip back and forth can be modeled well with negative numbers...

Exponentials first arise out of a need for a shorthand for multiplication (much like multiplication itself can be seen as a generalization of a shorthand for addition). Lets say we have a numberawhich we've multiplied together a bunch of times to getb: ...
The calculator uses the quadratic formula to findsolutions to any quadratic equation. The formula is: −b±b2−4ac−−−−−−−√2a−b±b2−4ac2a The quadratic formula calculator below willsolve any quadratic equationthat you type in. Simply type in a number for 'a', 'b...
Since division by a negative number usually generates no problems, we could be good conventionalists and not worry about the matter. However, it does sometimes generate problems and paradoxes. First of all, there is the paradox of the equation -1/1 = 1/-1. Here we have a quantity that...
