lets assume I have 3*4=12, why if I multiplying grater numbers from 3,4 I will get equal amount greater than 12 .. in other words if I multiply 4*4=16 so once I increase one of the operand which was 3 to 4 I got equal value 16 which is greater than 12 (3*4) .. so why once increasing the multiplicand operands(two operands) I get greater value?!

is the multiplying function that's increasing once we increase the input?! how can I visualize it?!
