In other words, minus minus results in a positive increase a. Minus a minus is exactly the same as plus a plus, e. This is a good time to mention that in mathematics, two negatives equal a positive when applied to minus a minus subtraction, or any multiplication, or any division. Spreadsheet software or applications will happily do the arithmetic and sort out the negatives versus the positives for you once you have replaced all the variables.
It even knows to do the innermost before the outermost, etc.
As an example, suppose you have simplified an equation to the following mess:. The spreadsheet will immediately solve the equation and give back the answer of If you have the software or Google Drive access, go ahead and try it. If you are really good at spreadsheet calculations, you can, of course, do equations with the variables still in place; substituting the variables with cell locations or range names.
At this point the equation becomes invalid. An equation immediately becomes invalid when a divide-by-zero scenario occurs.
Software applications are designed to recognize this when it happens. Plugging whatever-divided-by-zero into a spreadsheet used to give interesting results, before applications were modified to detect this. The basic concept of algebra is just plugging the numbers into the variables, and then doing the arithmetic. One merely keeps simplifying the equation until it is solved.
You now have a full understanding of that concept. Yes, you have been using variables since the first paragraph. Here is the last example. It is presented in a different format. The question, however, remains the same.

What is X? You already know everything needed to solve this equation. Whenever you change the actual value on one side of the equation, you must do the same on the other side of the equation. The same rule applies for addition, multiplication, and division. So we multiply both sides of the equation by 8. To find out, we go back to the original equation and replace X with We then simplify reduce the equation as before to its simplest form. There is a lot more a very lot more to algebra, but it is really only an expansion of what you have already learned.
Algebra is the basis of all other mathematics; including geometry, trigonometry, calculus, and so on. A good understanding of algebra is required to succeed at the other mathematics. Mathematics, itself, is the foundation of most other disciplines. This foundation is not just necessary for the sciences such as physics, electronics , chemistry, biology, astronomy, and so on. A mathematical foundation is necessary for many careers; including marketing, economics, architecture, and many, many others.
The variable,"f", times a negative 2.

I ma closer now than ever. Thank you. I tried and tried and tried to 'get' algebra. Took it in high school, didn't get it; dropped the class because I didn't want an "F" on my transcript. Tried again as an adult in community college.

Monopolized the teacher's office hours; became well-known in the learning center; hired a private tutor. I still couldn't grasp it. It seems so arbitrary. Your explanations make the very basics of addition and subtraction clearer, but I still am flummoxed by the division and multiplication. I suck at basic math in the first place. I understand in English grammar, how a double negative negates the statement, for instance, "She doesn't have no sugar," ends up meaning she does have sugar. But, in my mind, it just doesn't seem to translate across to numbers, and make sense. That's where I always thought it seemed arbitrary, and why I fall flat on my face every time; because I'm trying to make sense of it, and I can't.
That, and each new problem looks so different that I can't seem to apply the formula, becuase it isn't parsed English grammar term; don't know if it applies to math , just like the example problem s. Geometry was invented first!!! I was always bad in math especially algebra , this really helps, but my question is , is there a book I can buy using these symbols? I did 5 line papers with this and I hope my mom is proud when she sees all the work I did.
Im so thankful for all the help an support,i have a big test coming up,was so worried,but now ,i feel so secure,thanks for ur help. Math was always a weak subject for me.

This would be helpful and useful for anyone who's struggling with it. Voted up for useful! Where were you when I was struggling with Algebra in 7th grade? And you even have pictures. I tried so hard, I used to stay after school for extra help. Finally the teacher agreed to pass me with a D if I would stop coming.
I thought it was a good deal, although I was an A student in other subjects, I just couldn't grasp it. My son is now a teacher, and tells me she was a failure as a teacher for not trying harder! Hi there! I could have sworn I've been to this website before but after browsing through some of the post I realized it's new to me. Anyways, I'm definitely delighted I found it and I'll be bookmarking and checking back frequently! Hope this was helpful. Good hub on algebra, I hate it though, I speak like 5 languages but can never do math. Have a lot of respect for people in the science field.
