Maths is such an easy thing to deal with :  [4^2+3^2 = x^2 => 25 = x^2 ==> X=5] |

Math is so easy. I can't believe you are stuck on that problem. You should be able to do that in your head at 14.

I loved math.... was great at it till I hit college, and enrolled in the wrong honors math class..... opps.... had to MEMORIZE all the equations, and only could use a small little calc, no graphing calc. Oh well....
KMAN, are you familiar with PEMDAS? Thats what you use to solve for X....
(this is dumb, but it is a trick to try an remember it.... learned this about 12 or more years ago.....)

When working equations, you are supposed to work from left to right with PEMDAS, addition & subtraction being last.....
The "work" is shown in bracets [].
2x + 8 / 2 = 14
multiply both sides of the equation by 2......
[2x + 8 / 2 * 2 = 14 * 2]
2x + 8 = 28
then subtract 8
[2x + 8 - 8 = 28 - 8]
2x = 20
divide both sides of equation by 2
[2x / 2 = 20 / 2]
x = 10
Fairly simple.... do a few problems, and you'll get the hang of it.

Yes. All elementary math learns must remember PEMDAS. It will help you when you get to higher level math.

| over here we were taught basically the same thing but we called it BIMDAS (where B and I stand for Brackets and Indices respectively).
mssssee2 we actually had someone do that in an exam at my high school!

Don't worry, he'll be back. It is a suspension, not a perm ban.
