Показать описание
algebra from abstract to concrete uses wooden blocks to show the meaning of (x+y)**3.
(x+y)**3 = (x**3) + 3(x**2)y + 3(y**2)x + (y**3)
For this case x = 2 unit and y = 3 unit. (x+y)**3 = (2 + 3)**3 = 125.
In this video, we used wooden blocks to represent the mathematical symbols clearly to show the learners.
