An equation would look like this:
x+1=3
An expression would look like this:
x+1
As you can see, an expression has no equal sign. Conversely, an equation does. That is the primary difference between a(n) (algebraic) expression and equation.
2000 - 400= 1600 * .10= 160+400= $560 is probably right, but I pretty much guessed on how to get that.
