  1. Expressions and equations are different because expressions have an equals sign and equations don't.

  2. Expressions and equations are different because one has equal signs and that's expressions that have equal signs and equations dont have equal signs.

  3. Expressions and equations are different from each other because, expressions have a equal sign at the end to solve the problem. A equation does not have equal sign at the end, you know what you are gong to solve but don't have the answer.Hailey

  4. Expressions have no equal signs.And equations have equal signs.

    Expressions are different then equation because expression don't use an equal sign,and equations do use an equal sign.

  6. Noah:Expressions and equations are different because expressions have no eaul sings.With an euation you are supposed to solve it,and with a expression you are not.Equations have an eual sing.Ezpressions usually use variables.

  7. The diffrance of expressions and equations is. Equations are when you solve the proplem. And expressions where you write a problem or 2 and you don't solve the answer. thats the diffrance.

  8. One way that expressions and equations are different are that expressions have the math problem but no equal sign and equations have the math problem and an equal sign with the answer.

  9. Gracee: Expressions and Equations are different because Expressions don't have an equal sign. Equations has a equal sign.That is the difference between Expressions and Equations.

  10. Expressions and equations are different because expressions don't have a equal sign so a expression could be x+4. And a equation has a equal sign so a equation could be x+4=10.

    The difference between expressions and equations is that expressions has an equal sign and expressions has plus or minus signs. For example x=5 is an expression and x+5 is an equation.

  12. Expressions are different from equations. I know this because equations have equal signs. Expressions do not have equal signs.

    Expressions are different than Equations because, expressions don't have an equal sign.Equations have an equal sign. Here is an equation: v+8=. Here is an expression: v+8.

  14. Expressions and equations are different because with expressions, there is an equal sign. Equations are just the problem.

  15. Expressions and equations are different because equations have no equal sign.also with equations you don't solve it.And you do different methods for each thing.And last 1 method is easy and 1 method is hard.that is why they are different.

  16. Expressions and equations are different because,expressions dont have an equals sign. An expression can be s+6. An equation is different because it has an equal sign. An equation can be s=2+4.

  18. Expressions and equations are different because equations have an actual answer and Expressions don't. For example: n+7=9. Notice that there is an equals sign and a expression doesn't.

  19. Expressions and equations are different because expressions can have numbers and letters but no equal sign but with equations you can have letters, numbers, and a equal sign.

  20. Equations are signs that numbers and letters has. Expressions that don't have any signs. The differences of them is that, expressions don't have any signs of what to do or say but equations are signs that say or gives examples.
