a numerical expression is just an expression without any equal or unequal signs, e.g. (a+2b)c or 5x-6y
an equation shows two expressions with an equal sign, e.g. (a+2b)c = 53 or 5x-6y = 3k2-7k+21
it has to have an x number in it.
The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
abs(9 - 3)/2
An expression can have multiple outcomes, such as 5x+2, whereas an equation is a pair of expressions that equal each other, and can be solved, like 5x+2=12.
Expression has no answer. a equation has an answer
it has to have an x number in it.
A variable expression includes variables.
The variable.
algebric uses variables and numerical uses numbers
The variable.
An expression has no equal sign whereas an equation does have an equal sign
An equation has an equal = sign whereas an expression does not.
An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.
an equation has an equals sign.
The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
