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.

An expression consists of algebraic terms and has no equality sign

The numerical factor of a term is called the "coefficient."

algebric uses variables and numerical uses numbers

They are both expressions.

These two are both similar because they are both expressions.

Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.

Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.

Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)

Numerical: numbers only such as 10 + 2 = 12, or 14/7. Algebraic: primarily symbolic but may include numerical values or constants. E.g. y = x3 + x2 + x + C. A = T(1 + dt).

Algebraic expressions are terms that do not include an equality sign

no algebraic expressions do not have equal signs but equations do.

There is only one extra rule to algebraic expressions over normal numerical expressions: when two letters are next to each other it means multiply them together: ab means a times b The multiplication symbol is omitted as it looks too much like the letter 'x' can could be confused as such.
