Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

How do you remember number of pi?
You cannot remember it exactly because it has infinitely many digits, You are rarely required to know it to more than a few digits. 3.14 or, if you really want to be accurate, 3.14159 is good enough.
Remember that if you are trying to work out the area of a circle, the radius or diameter is likely to be accurate to at most 3 significant figures. So any gain from using a very accurate value of pi will be lost when the radius is only approximate.
yes it is an odd number because the last number in the entire number is an odd number

This is because they can only be timesd by 1 and themselves to be the answer of a multiplication of whole numbers. E.g. you can't get 11 by timesing 2x5 or 2x6, you would have to multiply a decimal number to get 11 as your answer.
How many 5 digit numbers can you make from the digits 650271?
First we'll find out how many combinations are possible if zero was another integer. In the ten thousands place, there are six possible numbers. In the thousands place, there are five possible, hundreds four, tens three, ones two.
6! = 6 × 5 × 4 × 3 × 2 = 720 possible combinations
There are 720 combinations of six different digits, but some of those possibilities have zero as the first number, in which case you've made a four-digit number. So now we need to find how many four digit numbers can be made with the digits 650271. The first digit can only have one possibility (zero). The second digit can have 5 possible, the third 4, the fourth 3, the fifth 2.
1 × 5 × 4 × 3 × 2 = 120
720 - 120 = 600
