Expression has no answer. a equation has an answer
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 expression has no equal sign whereas an equation does have an equal sign
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
equation
algebric uses variables and numerical uses numbers
Expression has no answer. a equation has an answer
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 equal = sign whereas an expression does not.
An expression has no equal sign whereas an equation does have an equal sign
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
An expression does not include an equals sign (=) For eg: 2x+3 would not be an equation but an expression However, 2x+3=0, is definitely an equation with a solution x= -3/2. An expression does not have a definite solution. An expression is a set of terms with mathematical operations combining them. An equation consists of two expressions with an equals sign between them. An expression is a collection of terms and does not have an = sign An equation is a collection of terms but has an = sign between them.
equation
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."
An equation states that an expression is equal to either a number or another expression.The 'equals' sign ( = ) is the tip-off that you have an equation.
