Pi is a mathematical version of 3.14. The official celebration of Pi is on March 14. It's funny because 3.14 is sort of like 3/14, the numerical version of March 14. Anyways, there are little information that I know of Pi, however, that's better than nothing at all. 

There are many things that Pi does, especially in math. Those who don't know what Pi is, usually mistaken it for "pie." However, that's getting off topic. Anyways, Pi can be used in finding the radius of a circle. They usually multiply the number by Pi. Ever since I entered middle school, Mr. Dorman has been REALLY excited about it. He's been testing kids on saying how many digits they remembered, and it's really hard since there's more than 100 numbers.

Pi is a very important thing in the math system of today. Sure, it may be used just for circles, but it can be used for other things too. We just don't know how yet.

So lately in math we've been learning about slopes. The formula of slope is y=mx+b.  The way to solve this, is to remember that m=slope, and slope is rise over run (rise/run). 

First of all, we need to know what the slope is. In this case, we are going to use y=7/4x + -8. First, you have to have a four quadrant graph. Look for -8 on the graph, and mark it. Then, use the rise, which is 7. Since it's not a negative, you go up 7 units. Then when you're done, you go right 4 times, since it's not a negative. Remember, if it's negative, then it goes the opposite direction.

Slopes and hills are actually easy, as long as you follow directions and do it the right way. Remember, the effort may seem meaningless now, but it will pay off in the future.

Equations are not that hard at all. It all depends on the question or problem. You can create your own equation for anything, like y=x-7. Of course, the majority of equations are mostly used for school. 
         What are some questions you can use for equations? Well, there are many of them actually. However, let's ask ourselves our own questions. The equation for now is y=6x. If you get 6 dollars as an allowance for one week, how much time will it take to save up for 18 dollars? Now let's see. The "x" stands for week. So we should substitute a number for each week. Since you get 6 dollars per week, it would be 6x1. What happens if it's 2 weeks? If you multiply 6 by 2, then it would be 12. Keep going until you get to the number you're looking for. There are many questions and answers the world might ask just for this equation, so you should do your best and prepare for that.
