Multiplication and Division Basics

Multiplication is ‘Repeated Addition’ of ‘one number’ the ‘other number’ of times.
x*y = x+x+x+..... ‘y’ times

Division is ‘Repeated Subtraction’ of second number from the first one, till the answer becomes less than the second number.
x/y = x-y-y-y-.... till the answer becomes less than ‘y’. Here the final answer what we get is called the ‘Remainder’ of the division. And the number of times subtraction is carried out is called the ‘Quotient’ of the division. Here ‘x’ is called the ‘Dividend’ and ‘y’ is called the ‘Divisor’.
