Every number equals to one when is powered by the zero.
it depends what the number is
At least means it can be larger than or equal to.
X >= 15
No more than means less than or equal to:
X <= $7
1km=1000metres
15km=15000 metres
15000/600=25
25-1=24 (minus the last one)
hope this helps :)
42.50$ ? 21 times 1.25 plus 13 times 1.25 = 42.50?
