Question

Question is as follows. How can I transform 124 to 7?

Answer 1

Firstly it is needed to get numbers 1, 2, 4 using the initial number 124.

To do so, we need

• to get an integer number using the division of 124 by 100. That way we get a number 1 and remainder of the division 24

$124 / 100=1$ (integer number) and $24$ (remainder of the division)

• Then we should get an integer number with a help of dividing 24 by 10. That way we get a number 2 and remainder of the division 4

$24/10=2$ (integer number) and $4$ (reminder of the division).

Now that we have the numbers 1, 2 and 4, we should add them up to get 7:

$1+2+4=7$
