The answer depends on the type of grass you're planting. Cool-season grasses grow best when temperatures are between 60-80 degrees. Early fall is the best time to seed because of its shorter days, cooler nights, and heavier dews.
The definition of odd is given by 2n+1, where n is an integer. So if n=0: 2(0)+1 = 0 + 1 = 1 When n is 0, you get the first smallest positive integer, therefore when n is 45 you'd actually get the 46th smallest positive real integer. Therefore, the 45th smallest positive odd number is given by: 2(45-1)+1 = 2(44)+1 = 88 + 1 = 89 Note: the -1 represents offsetting the numbers, because we begin counting at zero. The answer is 89.

Actually, zero is neither a negative or a positive number. The whole idea of positive and negative is defined in terms of zero. Negative numbers are numbers that are smaller than zero, and positive numbers are numbers that are bigger than zero. Since zero isn't bigger or smaller than itself (just like you're not older than yourself, or taller than yourself), zero is neither positive nor negative.
