Find the easiest way

Take a simple fraction. 2/2 =1. 3/3 =1. Any number divided by the same number equals one. Let's make it a little harder. 2x2/2x2 = 1. When you multiply and divide then the order you do things doesn't matter. If you take the same equation 2x2/2x2 = 4 Do the multiplication first and you end up with 4/4 =1. So if you are someone who finds multiplication a lot easier than division then this may be the method for you.

Lets make it a lot harder. What about 27x27x27 / 27x27x27 = ? Clearly the multiplication is a lot harder, but in this case the division is just as easy. 27/27=1, so you end up with 1x1x1 = 1.

Mathematics has right and wrong answers. There are many ways of finding mathematical answers and some methods may be just as easy as others. Watch Countdown and you will see contestants with the same answers but different methods. Obviously the method they chose was the easiest for them. Be aware that sometimes there is one particular method that is the easiest. You can learn with experience just like the 27x27x27 example.

That sums it up.
