There are a few rules for simplifying an algebraic expression. Specifically, one should combine like terms, and then they should try to isolate the variable by doing the opposite, either multiplication or division.

There is no opposite it's an adjective.

In many ways. It really depends on the algebraic expression. If several terms are added/subtracted, you can usually combine similar terms (terms that have the same combination of variables). If variables are multiplied, you can combine the same variable, adding the corresponding exponents. Sometimes expressions get simpler if you factor them; sometimes you have to multiply out (in other words, the opposite of factoring). Quite frequently, you have to use a combination of methods to simplify expressions. Take an algebra book, and look at some of the examples.

Expressions do not have equal signs, but equations do. Just think: "Equations are equal!" CX expression is kind of like an expression. example (56+49). think of the x in e(x)pression as if it's marking out the equal sign as not to be used. Equation is kind of easy. Opposite of expression. example (56+49=105). think of the O in equati(O)n as if it's circling the equal sign as to be used.

Yes. Subtraction is the same process as adding the opposite. For example, take the expression 9 - 4. The opposite of 4 is (-4). 9 + (-4) is exactly the same as 9 - 4. This relationship is a fundamental concept of early math development, and is often poorly taught in the primary grades.

Usually they are opposite processes. Factorisation is taking an algebraic expression and partitioning it into factors in brackets (or parentheses). Expansion is taking such brackets and multiplying them out to a simple - if lengthy - expression.

Increased.

Opposite of the sum is not a mathematical expression and I can only assume it means the difference.So,5x - x < |x - 5|Or 4x

decreased? the opposite! During 2011 the FN became more popular.

You could say that you are being "opposite of how other people are" on Opposite Day. If you say the opposite of an opposite, it is a true expression.

Increased is a reasonable antonym, considering that decreased is a synonym.

Mispronunciation. In mathematical terms, the opposite would be a group of words, since expression can mean a group of mathematical symbols representing a number or quantity.
