The content ranges from extremely difficult algebra and pre-calculus problems to problems in branches of mathematics not conventionally covered in secondary or high school and often not at university level either, such as projective and complex geometry, functional equations, combinatorics, and well-grounded number theory, of which extensive knowledge of theorems is required.
[1] [2] [3] By contrast, discrete mathematics excludes topics in "continuous mathematics" such as real numbers, calculus or Euclidean geometry. Discrete objects can often be enumerated by integers ; more formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets [ 4 ] (finite sets or sets with ...

So, if you have two guinea pigs, you’ll need a 10.5 sq. ft. enclosure to give them plenty of room. It must also be well-ventilated with a floor they can easily walk on. They also need time ...
Visual proof for the (3, 4, 5) triangle as in the Zhoubi Suanjing 500–200 BCE Oracle bone script numeral system counting rod place value decimal Shang dynasty (1600–1050 BC). One of the oldest surviving mathematical works is the I Ching , which greatly influenced written literature during the Zhou dynasty (1050–256 BC).
m × 10 n. Or more compactly as: 10 n. This is generally used to denote powers of 10. Where n is positive, this indicates the number of zeros after the number, and where the n is negative, this indicates the number of decimal places before the number. As an example: 10 5 = 100,000 [1] 10 −5 = 0.00001 [2]
