since pi is a a circle's circumference and a number that is neverending and mathematically goes on endlessly, doesn't that prove with math that our universe is some type of endless circle?

I have a math disorder which prevents me from figuring out this math problem. I want to know when someone makes 90,000 a year, how much is that hourly?

Greetings,

I would like to ask how one would improve at mathematics.

The reason I ask is because I consider myself extremely bad at maths. It's not a matter of being lazy, either. Whenever I'm given homework, I can solve the basic problems quite easily. However, at even slightly complicated ones, I'm stuck. I spend hours and hours trying to figure it out - I write and erase and try a lot of stuff - it hardly ever works. I don't always spend all my time on that single problem; I often go through other similar ones, and go back to the original problem, yet I still can't find any loopholes.

When the solution is given to me, I'm like "Duh!". Even from there, when I'm given a slightly more complicated one, I'm stumped again.

I don't like to repeat myself, but I have to emphasize that this is not a matter of laziness on my part.

Thank you.

p.s. Any indirect methods, such as games, books, philosophy, etc. (even more radical ones), are also appreciated. Thanks.

2x - y = 8

I don't need the exact value of x. I need the formula

I already answered one of these types of questions, and the answer should look something like this:

Solve for c: p = a + b + c
Answer: c = a + b - p
