A = 49.0 rounded to 1 DP

b= 7.62 rounded to 2 DP

Find the minimum of a - b

a-b

49.0-7.62

41.38 right or wrong tell

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

is this part of a question or something
