If there are two jobs such that one them can be completed in m ways and second job can be completed in n ways, then the two jobs in succession can be completed in m X n ways. and the two jobs are independent of each other that is the occurrence of first job does not effect the occurrence of second job.

Students / Parents Reviews [10]
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
