algebra is important because we use it daily with out even knowing
for example:
Sample Problem: x + 9 = 18 - 2xSolution: x = 3
for example, if you have 2x you can write it as : 2 times x or 2 multiplied by x.
no algebraic expressions do not have equal signs but equations do.
Algebraic expressions are terms that do not include an equality sign
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
In algebraic expressions, it is acceptable to omit the coefficient of 1 when it is in front of a variable. For example, instead of writing (1x), you can simply write (x). This convention helps simplify expressions and makes them easier to read. Additionally, in multiplication, expressions like (1 \cdot x) are often written as just (x).
the word algebraic is arabic.
Yes. That is the definition of an algebraic expression.
Only like terms can be subtracted or added in algebraic expressions.
