The same is true with “style” in math. One type of method—sometimes algebraic—is usually most appropriate for solving a particular type of problem. But styles are much harder to recognize, point at, and label than things—which is why recognizing and labeling algebra can be tricky. So ...

What is algebra, exactly? Is it one of those three-cornered things?J. M. Barrie
The goal in algebra is to find out the unknown and in order to do so in this example, you would manipulate the scale of the equation to isolate x on one side of the scale by adding 37 to both sides, resulting in an equation of x = 50 meaning that you started the day with 50 ba...
Abstract algebra is one of the divisions in algebra which discovers the truths relating to algebraic systems independent of the specific nature of some operations. These operations, in specific cases, have certain properties. Thus we can conclude some consequences of such properties. Hence this branch...
So if we take 7 away from one side, we have to do the same thing to the other side of the equation:. So here’s what we have left: You don’t need pictures to do algebra. What you need is a way to use the operations that you already know (addition, subtraction, multiplication,...
WK Nicholson,ES Campos - 《Journal of Algebra》 被引量: 306发表: 2004年 Nonpositive curvature and reflection groups A space is aspherical if its universal cover is contractible. The main purpose of this paper is to describe a new class of examples coming from the theory of reflection groups...
This is a variation of the quadratic formula. Similar procedures appear as far back as Babylonia, and represented the state of algebra (and its close ties to astronomy) for more than 3,500 years, across many civilizations: Assyrians, in the 10th century B.C.; Chaldeans, in the seventh ...
