Sarita and Ameena decide to paly a game of expressions. They take the variable x and the number 3 and see how many expressions they can make. The condition is that they should use not more than one out of the four number operations and every expression must have x in it. Can you help them? Sarita thinks of (x + 3) Then Ameena comes up with (x - 3) Is (3x+5) allowed? Is (3x + 3) allowed?
