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.

What is the square footage of a 60 foot radius circle?
Archimedes proved that the area enclosed by a circle is equal to that of a triangle whose base has the length of the circle's circumference and whose height equals the circle's radius. Circle area therefore comes to π(pi) multiplied by the radius squared.
area = (pi) * (60)2 which is the same as 3.14 * 3600 = 11304 square feet.
What is the radius of the circle whose equation is 3x² plus 3y² equals 75?
3x^2 + 3y^2 = 75
Divide both sides by '3'
Hence
x^2 + y^2 = 25
x^2 + y^2 = 5^2
In the Pythagorean Geometry
The circle equation is
x^32 + y^2 = r^2
Hence 5^2 = r^2
Hence r = 5 (The radius)

What is the difference in volume between a 13 ft cube and a 10 ft cube?
A cube thirteen feet to a side has a volume of 2197 cubic feet. A cube ten feet to a side has a volume of 1000 cubic feet. The larger cube has 1197 cubic feet, or 119.7 percent, more volume over the smaller one.
1. Whenever you divide a number by itself, the answer is 1, except when dividing by zero.
What is the volume of a box that is 12cm long and 6cm wide and 4cm high?
To calculate the volume, multiply the length x width x height.
volume = 12cm x 6cm x 4cm = 288cm3

What are the factor pairs of NEGATIVE numbers?
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.

Alvin's age is three times Elga's age The sum of their ages is 76 What is Elga's age?
a = 3e
a + e = 76
∴ 3e + e = 76
e = 76/4
e = 19
∴ a = 3 × 19
a = 57
Alvin is 57 years old, and Elga is 19
you divide by 1000 to convert from cm3 to dm3, so 100cm3 is 0.1dm3
45 - 15 = 30 is one way of writing the subtraction.
Another way is :-
45
-15
Subtract the 'units' column ; 5 - 5 = 0
Hence first part of answer is
45
-15
XXX 0
Then subtract the 'tens' column ; 4 - 1 = 3
Hence the full answer is
45
- 15
=30 The same answer!!!1
