    You typically learn it in high school. Middle school math is typically pre-algebra, although you may dip your toes in algebra when you're in 8th grade if you're taking an advanced class or something.

    Yes, absolutely. The courses even build on one another. It's sort of like a pyramid, and if you want to learn calculus at the top, you'll need the algebra underneath it.
  • Question
    If b=2, what is 10b squared?
    Community Answer
    Community Answer
    If you're asking about 10b², it's (10)(2)(2) = 40. If you're asking about (10b)², it's (10 x 2)(10 x 2) = 400.
  • Question
    I absolutely suck at math; I don't understand a word the teacher is saying. It's hard for me to fully understand websites like this. Any advice on how I can improve?

    It sounds like you could definitely use the services of a good tutor. (A "good" tutor is one who can sense that a student is not grasping a concept and is adept at adjusting an explanation until the student does understand.) If you don't want to pay for such a service, perhaps you could find a friend or relative who understands algebra and who's willing to spend some time helping you. (Remember that just because someone understands a topic does not mean s/he is good at explaining it!)

    What if I have a test coming up but don't get it?

    Ask your teacher things you don't get, or ask classmate or friend for help. Maybe even stay at lunch or after school with your teacher so you can fully understand it. You could always find Khan Academy videos that are helpful.

    Yes, many times.
  • Question
    Why do you have to reorder some algebraic questions before you can answer them, and not others?

    It was discovered long ago that algebraic equations are most easily solved by following certain steps in a particular order.

    The easiest way is to read an algebra textbook and understand each concept as it's presented. You could also hire a tutor.
  • Question
    I do not understand any math whatsoever; this is so hard for me. Anything I could do to improve?

    If you're completely lost, all you can do is hire (or find) a tutor, and start over again at the beginning. That may mean you'd have to review several years of math! This would be time-consuming, so you have to decide how important this is to you. It might be worth it simply for the self-confidence you could gain.
  • Question
    How do I figure out percentage?

    Community Answer
    A percent is always out of 100. Think about this: per means divide and cent means 100 (100 cents is $1).
  • Question
    How do I solve k/4 - k/3=7?
    I_l1ke_gam3s
    I_l1ke_gam3s
    Community Answer
    Multiply both sides by 12 to eliminate the fractions: 3k - 4k = 84. -k = 84, and k = -84.
