Sometimes algebraic expressions can be simplified – this means that we collect all the similar terms together. We would never say in conversation “I have 3 apples plus 2 apples”. Instead we would say, “I have 5 apples”. Similarly in algebra we can say:
3 + 2 = 5
However, if I had 5 bananas and 2 apples, it would be impossible to write this in a simpler way.
