    Expression and equations are different because expressions do not have a equal sign and equations have a equal sign.

  2. Expressions and equation are different because when you write a expression you do give a answer to the question. When you do a equation you do solve the problem and show your work.

    The difference between expressions and equations is that expressions are math problems that don't have answers. An equation is a math problem that has an equal sign and the answer.

  5. Expressions have an equal sign and equations don't. Expressions also have an answer and an equation doesn't. An equation is where you do something like x+2=5. An expression is where it shows the answer to the problem.

    The difference between expressions and equations are that equations have the answers in the problems. On the other hand expressions have no answer and is just the number problem.

  8. Expressions are different than equations because equations has the all the signs that are in math for example multiplication sign, division sign, subtraction sign and Etc. Expressions don't have the Math signs.

    The difference between an expression and equation is that an expression an equal sign or answer but an expression has an equal sign and an answer.

  10. Expressions are different from equation by equations have equal sins and answers. Expressions don't have a equal sin or a answer.

  13. Expressions and equations are different. Because expressions don't have a equal sign and equations do that is how they are different.

    The difference between a expression, and a equation is that expressions have no equal sign or answer, and a equation has equal signs, and answers.

  16. Expressions and equations have different stuff. A Expression is 2+3 not showing the =. A equation is 2+3=5 showing the = . Expressions and equations are different.

    Equations and expressions are different because a equations have an equal sign. A expression is an unsolved problem with no equal sign. This makes them different although they can each have variables, constants and coefficients.

    Equation has equal sign and the answer and the expressions does not have the equal sign and the answer.

  20. They are different by expressions are the answer like 2+2=4 or 3+3=n. Equations are like 9X9=81 they are like any type of addition, subtraction, division and times.

    Expressions and equations are different because, when you are doing an equation you would put a equals sign at the end. When you are doing a expression then you would put the word equals or is. Also when you do an equation then you would show it as something like: x= 31+2. When you do an expression you write the whole thing out in words and not the number sentence. Also the final thing that is different between the two is that an expression does not have any numbers but an equation has no words.

  23. Expressions are different from equations because expressions have the answer to the equation.
    Ex. Expression: 5x4=20
    Ex. Equation: 5x4=T
