An expression is just some combination of numbers and symbols....example.........

 

3 + 5

2x - 9

5x^7 - 2x^2 + 3

sqrt(3) + 28  .

etc.

 

An equation implies an "equal" sign  with an expression on each side of the sign....example....

 

2x = 8x - 3

5x - 9 = 4x - 2

sqrt(3x)  = 25

etc.

 

 

 

cool cool cool
