n is an integer and n2 < 39
Quantity A: The greatest possible value of n minus the least possible value of n
Quantity B: 12
My Approach:
greatest value of n = 6.2
least value of n = -6.2
In the above case A is the answer but the answer is C
greatest value = 6
least value = -6
Hi! Can someone explain why n cannot be 6.2?
Thanks in advance
