∙ 11y ago
An expression does not equate to anything. An equation is equal to something.
Expression:
x+2
Equation:
x+4=2x
Equivalent expressions:
x+2 and 2x-2 if x=4
Equivalent equations:
x+4=2x and -x+10=2x if x=4

What is the difference between arithmetic operations and logical operations?
Arithmetic operations act on the values of numbers or expressions. Logical operations act on the truth-values of statements or equations.
Is this a expresion or equation 3a - 14 4?
As far as I know it's an expression because it doesn't have an equal sign. That's the main difference between expressions and equations.
What is the difference between a linear quadratic and a quadratic quadratic?
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
What in the difference between a numerical and algebraic expression?
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
Solve the expression 3i 5-2i?
Expressions cannot be solved. Only equations or inequalities may be solved. Also, there is no symbol between 3i and 5.
What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
Is there a difference between rational expressions and rational equations?
Yes. An equation has an "=" sign.
What are the similarities between equations and expressions?
Both have a value
What is the difference between arithmetic operations and logical operations?
Arithmetic operations act on the values of numbers or expressions. Logical operations act on the truth-values of statements or equations.
What is the difference between two logic equations being equal versus two logic equations being equivalent?
Equal is the truth table and the circuit are the same. Equivalent is when the truth table is the same but the circuit is different
Is this a expresion or equation 3a - 14 4?
As far as I know it's an expression because it doesn't have an equal sign. That's the main difference between expressions and equations.
What is the difference between inequalities and equations using adding?
equations have an = sign, inequalities do not
How are algebraic expressions and equations alike?
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.
What clues could help determine between equations and expressions?
An equation has the 'equals' sign ( = ) in it. An expression hasn't.
What is the differences and similarities between equations and expressions?
Expressions are: General little statements that DO NOT have an equal sign: 2x-4 2m^3+5 Seven less than half a number squared Twice the difference of a number and five. Equations are: Any statement that DOES have an equals sign(or equivalent): 4n+7=11 1/2 b-2=3 Twice a number increased by four is ten The difference of a number and two is five Equations and expressions are similar because they both have a value. Equations and expressions are different because a equation is on sentence, and an expression is a phrase. An equation has a relation symbol, and a equation has no relation symbol. Example for equation: 1. 10 is five less than a number. 10=x-5. 2. A number is less than five. x<5. Example for expression: 1. A number less than five. x. 2. Five less than a number. x-5.
What are four equivalent expressions for 50-10?
60
What are the difference between elactric field and electric displacement field?
The electric displacement field is a vector field, shown as D in equations and is equivalent to flux density. The electric field is shown as E in physics equations.
