Each of us have had some trouble with math once in a while right? It could be multiplication, division, or even subtraction, like me. Subtraction and I don't get along at all. It's always been hard for me. I'd always add or multiply by accident with, still do actually. I just try my best and I'll use my fingers, pictures, or something to help  me figure it out.


One strategy I worked out with subtraction is the fingers, it helps me count backwards so that I see that it's being taken away. I'll start at ten or any other number with my thumb and count back. I just have to really pay attention to what I'm doing. It's a little frustrating, though. Another strategy I like to use is drawing pictures or tally marks. Once again, it helps me actually see the numbers being taken away. These strategies could help you to if you learn by doing something or seeing something.
 
You could use the Pythagorean theory to calculate how long and far it would take an enemy war ship to get to one place and help yourself choose the best course. You'd be able to make it to the destination before them and set a blockade to keep them away and make them retreat, possibly even surrender. You could also calculate how far and long it would take yourself to get the destination.


Another way you could the Pythagorean theory is by using it to see if you could beat your friend in a race to get a certain spot. Not to mention set up a slip 'n' slide for your friend and have them fall more than once. Or you could set up trampolines and jump from one to the next to help boost your time. Or you could always set up a hidden pit to stop your friend all together.
