  1. Expressions and equations are different because an equation has an equal sign while the expressions don't.

  2. Expressions and equations are different by how expressions do NOT have an equals sign whereas equations do have an equals sign.

  3. The difference between an expressions and equations is that an expression doesn't have an equal sign, while an equation does.

  4. Expressions and equations are different because. Expressions don't have an equal sign. Equations do have a equal sign. That's how expressions are different.

  5. Expressions and equations are different because equations have an equal sign and expressions don't. For example the problem 9+10=19 is an equation because it has an equal sign. The expression would be simply 9+10. SO they are different because an equation solves the problem and an expression is just simply the problem.

  6. Expressions and Equations are different because,In a expression, you have the problem, but you don't answer it. In a equation You write out the problem and then you answer it. These are the differences between Expressions and Equations. :)

  7. Expressions don't have the answer or an equal sign. Equation has the full problem iculding the answer and the equal sign.

  8. Equations have equal signs and expressions don't.

  9. Expressions and equations are different because an expression is when you don't find the answer, and an equation is when you do. In an expression, there is no equals sign, and in a equation, there is an equals sign. This is how expressions and equations are different.

  10. The different between expressions and equations is that an equation has a equal sign in the problem. Then an expression is the opposite of that and does not have an equal sign.

  11. Expresions and equations are different because, a equation has an equals (=) sign. While expressions on the other hand do not.

  12. Expressions and equations are different because an equation has an equal sign. A expression does not have a equal sign.

  13. Expressions and equations are different because an expression is where you solve a question and a equation is a problem.

  14. Expressions and equations are different cause one has an equal sign and the other has no equal sign and the one that has an equal sign is equation and an expression doesn't.

  15. Expressions are different than equations because an expression has no equals sign.While an equation has a equal sign.

  16. Expressions and equations are different because a expression doesn't have a equal sign at the end and a equation does. Also, a equation has a answer.

  17. Expressions and equations are different because and equation is the work that leads up to an answer and a expression is what has symbols and numbers.

  18. Expressions and equations are different because one has a equal sign and one doesn't. An equation has what you're adding, subtracting, etc. together and an equal sign with the answer. On the other hand, an expression is just the problem with no equal sign. Therefore, equations are different from expressions because of the equal sign.

  19. A expression does not have a equals sigh for example this is a expression: a+3.A equation has a equals sigh for example this is a
    equation:a+3=6.

  20. Expressions and equations are different by an expression having the problem with an equal sign and equations don't have a equal sign.

  21. Expressions and equations different because equations have an equal sign and an answer at the end.Expressions do not have an answer at the end.

  22. Expressions and equations are different because an equation has an equals sign and an expression does not. An expression in some cases would be the question being asked and the equation would be the answer.

  23. Expressions and equations are different because an equation has an equal sign and an expression doesn't. An example of an equation is 1+3=4. An example of an expression is 3x.

  24. The equations have and = sign and the end and expressions are Without a = sign. For example a expression looks like this --> A-9 and equations look like This --> 4-E (E=4) 4-4=0.

  25. Expressions and equations are different by an equation is the problem Wile your are trying to solve it.A expression is what you are going to do to figure out the problem.:)

  26. Expressions are different from equations because an expression is a math problem in the form of words and an equation is a math problem in the form of numbers and symbols.

  27. An equation that you need to solve and find an answer and there is an equal sign. An expression that you don't solve and there is no equal sign.

  28. the difference bettween an expression and a equation is that when you are trying to find the expression you dont have to find the answer. When you find the equation you have to find the answer.

  29. Expressions and equations are different because expressions do not have an equal sign and equations do.So equations you answer the questions and expressions you don't.

  30. Expressions and Equations are different because in equations it has a equal signs while in expressions there is not.
