Understanding Exponents and Area

Natasha Swanepool introduces a learning hack for intermediate phase students, explaining the concept of like objects in addition and subtraction. She transitions to algebra, introducing variables and basic operations. The video then covers calculating the area of a shape using length and breadth, followed by an explanation of exponent laws and why units are squared in area calculations.
