If you can always cut a number in half, and cut that in half, and cut THAT in half, doesnt that mean there are an infinite amount of numbers (or fractions of a number) between the number 1 and 2?

Also, how can you ever stand on one side of the room, and then walk out the door across the room, if there is an infinite amount of numbers in the distance between you and the door? I am so confused. Am I thinking about it the wrong way?

I'm 26 years old, and when i was in highschool, i never managed to get through the math classes - i tried my hardest to do the work, but i only know math as add, subtract, and some of the times chart.... i want to learn more, but don't have the money to pay for it. where's a good site that adults can use to learn math skills?

I'm never sure when it comes to this level of math.

The answer is 4. Your job is come up with problem and solution. The person that uses the most unique math operations wins, for example: 2+2 counts the same as 2+2+0. 2+2-0 wins over 2+2+0.


The catch: You may not use the same number twice. You may modify your answer anytime, but if it looks like someone elses in the end, then who ever posted the answer last will be disqualified.

Good luck !!

...what is.... i²....equal to?

"i" isn't a variable, but stands for "imaginary numbers" if i remember correctly (jeez, that was nerdy!)

i admit, it is a hard concept to accept but it does equal something!
