10 most difficult mathematics riddlesMathematics quiz
Which of the following Roman numerals stands for 4?
Both IV and IIII
None of the above
Both notations are correct and historically Roman numerals were often written less consistently than today. The notation 'IIII' is often seen on clock faces. The reason for that may be practical, to avoid confusing the IV and VI when the clock is held upside down (although other theories also exist).
What is the most important work of Claudius Ptolemy from the 2nd-century?
De revolutionibus orbium coelestium
The Almagest is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy (c. AD 100 – c. 170). One of the most influential scientific texts of all time, its geocentric model was accepted for more than 1200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus.
Which mathematician is it?
Gottfried Wilhelm Leibniz
Jules Henri Poincaré was a French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath, and in mathematics as " The Last Universalist"n since he excelled in all fields of the discipline as it existed during his lifetime. He was responsible for formulating the Poincaré conjecture, which was one of the most famous unsolved problems in mathematics until it was solved in 2002–2003 by Grigori Perelman. In his research on the three-body problem.
Which mathematician laid the foundations for abstract algebra (especially the group theory)?
Évariste Galois was a French mathematician born in Bourg-la-Reine. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem standing for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra, and the subfield of Galois connections. He died at age 20 from wounds suffered in a duel.
Which numeral system was in use in ancient Sumer and Babylon?
Remnants of the highly composite sexagesimal system are in use even today for time measurement and geometry. An hour of time is divided into 60 minutes, which in turn are divided into 60 seconds.
The illustration shows the figure known in mathematics as;
lune of Hippocrates,
In geometry, the lune of Hippocrates, named after Hippocrates of Chios, is a lune bounded by arcs of two circles, the smaller of which has as its diameter a chord spanning a right angle on the larger circle. Equivalently, it is a non-convex plane region bounded by one 180-degree circular arc and one 90-degree circular arc. It is the first curved figure to have its exact area calculated mathematically.
In maths, what is the power set?
the set of all the exponents of a set
the set of all the squared exponents of a set
the set of all the subsets of a set
the set of all the roots of a set
A set is defined as a collection of its elements so, if S is a set then the family of all subsets of S is called the power set of S and it is denoted by P(S).
