a variable is a symbol for a number that is unknown...it is usually represented by a letter.

The variable in the expression 5 - 4t is t.
t is the variable in this expresssions


a variable is something which can store data.

eg. t could be 4 or 7 or 4578.

5 and 4 (-4) are constants. this basically means they dont change value. because 5 cant be equal to 7 or 12 etc!

but t can be anything

therefore its a variable
