Each term in an algebraic expression is separated by plus & minus 5x + 4 = 12x has two different terms (5x, 4). Good answer. Actually the equation has three terms, 5x, 4 and 12x.
It could be: -3/8+4x-9z as an algebraic expression
By "inequations" I assume you mean "inequalities" because I can't think of anything else other than equations where the equation sign is crossed, and I don't think you mean that. Most algebraic operations work the same in equations and inequalities; one thing to be wary with is multiplying or dividing both sides of an inequality by a negative number. Take the inequality 3 < 4. If you multiply both sides by -1, you get -3 < -4, which is incorrect; so, when you multiply or divide both sides of an inequality, be sure to invert the inequality sign. Also, when the sign of an algebraic expression is ambiguous, I sometimes use the square of the expression, as the square of an algebraic expression not involving complex numbers will be positive; I do this to be a bit "surer" of the sign. However, this may introduce more problems, of which extraneous solutions are only the tip of the iceberg. Sorry for the rather unnecessarily verbose answer.

That they form an algebraic structure known as a ring.
The term algebraic sum is used when the numbers you are adding include both positive an negative numbers. Ordinary sums are done with positive numbers only.
Constants (numbers), variables, the four basic operations of arithmetic (+, -, *, /) as well as brackets and indices (including negative and fractional ones).
It would be -2 - x .
An expression is non polynomial if it has : negative exponent fractional exponent variable exponent in the radicand
2(-6n)
It could be: -3/8+4x-9z as an algebraic expression
-15 ----- n (-15 over a variable)
x+(-8)This simplifies to x-8
It is 8*(-4)N which is -32N

four times the product of negative three and a number
x is non negative and x is not greater than 0
It means that the term for which 3 is the coefficient is meant to be subtracted.
