Math and Arithmetic
Math is the study of abstractions. Math allows us to isolate one or a few features such as the number, shape or direction of some kind of object. Then we can study what can be learned about the behavior of those features while ignoring everything else about the object.
There is a bus with 7 children inside. Each child has 7 bags. Inside each bag there are 7 big cats. Each big cat has 7 small cats. All cats have 4 legs each. How many legs are on the bus?
As a riddle, the answer is zero legs on the bus since the bus has wheels instead of legs. But as a maths problem; It's not a tricked question -- just a straightforward maths problem Confirmed answer is 10990 legs. § Let's say the whole situation simply : - There are 7 girls. - Each girl has 7 backpack - Each backpack has 7 big cats - Each big cat has 7 little small cats. § Question: How many legs are there in the bus? § Let's focus on each part of the question systematically, write down on a piece of paper if you have to, following my steps of chains. 1. Focus on the first girl first: A B C D E F G Girl A has 7 backpacks 2. Now focus on first backpack A1 : A1 A2 A3 A4 A5 A6 A7 Backpack A1 has 7 big cats 3. Now focus on first big cat : 1 2 3 4 5 6 7 ? Each big cats have 7 small cats (that's the end of the focus) Systematically, 7 small cats has 28 legs (7 * 4) combined with the big cat that owns this 7 small cats. Let's call this the "cat chain", so cat chain 1 has 32 legs altogether. ? So since there are 7 big cats 7 * 32 = 224 legs ? Therefore each backpack has 224 legs ? Finally, each girl has 7 * 224 = 1568 legs. Lastly, since there are 7 girls, A to G, there are 7 * 1568 legs (per girl) = 10976 legs. Now, since each girl also has 2 legs each; SO, (7 * 2) + 10976 = 10990 legs altogether Note: Disregarding bus driver, buses and etc…Only focus on the girl and their backpacks! Or There are 7*7 = 49 bags and there are 7 + 7*7 = 56 cats in each bag, meaning there are 56*4 = 224 legs in each bag. So including the 7 children that have 2 legs each, there are 7*2 + 49(224) = 10990 legs in total.

How much tonnage air conditioner is required for 2779 sq ft?
It depends a great deal on where you live and how well your home is insulated. Square feet is not a great help when planning the size of an air conditioner. It is very useful to also have the cubic feet in the home, along with the sizes and types of windows. Where I live in the northwest US, a 3-ton unit would do the trick easily, but then, we do not get the intensely hot, long summers as you might in say, Phoenix.

What is the percent error formula?
Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make it a percentage. The percent error obviously can be positive or negative; however, some prefer taking the absolute value of the difference. The formula is the absolute value of the experimental value (minus) the theoretical value divided by theoretical value times 100. % error = (|Your Result - Accepted Value| / Accepted Value) x 100
