Question

How many times can you subtract 7 from 49?

Answer 1

7 can be subtracted fro 49 only one time....

Answer 2

Answer:

We can subtract 7 from 49, only 1 time.  

We know that, the square of 7 is 49, i.e., 7 times 7 gives 49. Thus, when we subtract 7 from 49 the first time we get 42.

Now, we can continue subtracting 7 from 42 and the number will keep reducing. Thus, it will no longer stay the same as 49. Thus, 7 can be subtracted from 49 only ones.
