Greek letters are used in math because they provide a way to represent specific mathematical concepts or variables that may not be easily expressed using the standard Latin alphabet. They are commonly used in mathematical formulas and equations to make them more concise and clear.
Science and mathematics use most of the letters of the Greek alphabet on a daily basis

There is no Greek symbol for anything.Greeks used letters and words, not ideograms. A ''symbol'' for family was the Goddess Hestia, one of the 12 Olympians.
There are no weird letters in maths. Greek mathematicians were responsible for a significant amount of the early mathematical work and they, naturally used Greek letters. Many of these letters are still used today. Just because you are not familiar with characters in the Greek alphabet does not make them "weird letters".

In math and science, Greek alphabet letters are used in formulas to represent various constants and variables. The Greek letter pi is used to represent the ratio of the circumference of a circle to its diameter.
The acceptable convention says uppercase letters are used for sets and matrices and lowercase letters are for variables, constants and vectors. Greek letters are mainly used for constants, such as pi=3.14 and e=2.718.
I am not sure what you want to know, but surely math is not just Greek. The ancient Greeks made great and fundamental contributions to math , particularly in Geometry and there are modern Greek mathematicians , but the field has expanded exponentially since the heyday of the Greek geometers -excellent mathematicians are now found all over the world. Mathematicians often used Greek letters, but this is only a notational convenience- has nothing to do with the Greek language.
Letters used in math are called variables.
The pi symbol is actually a letter of the greek alphabet. Many math symbols are letters of the greek alphabet.
Such a symbol is called a "variable". It can be a letter, a group of letters (especially in computer programming), or a letter with a subscript (a lowered number, or some other letter - this is more common in math). The letters need not be from the Latin alphabet; Greek letters, or sometimes Hebrew letters, are also used.
Pi ( π ) - used in geometry: ratio of cirle's circumferenct to diameter.Theta (θ) - symbol used in trigonometry, to indicate an angle measurement in degrees.Sigma (Σ) - used in math for summation of a series.Delta (Δ) - used to indicate a change in something.There may be others that I haven't listed. There are many more Greek letters used in the different science fields. Hope that helps.
In Greek letters, "yiayia" is spelled γιαγιά. It means "grandmother" in Greek and is a term of endearment used for one's grandmother.
Greek letters are used for population parameters. Eg: µ is the population mean English letters are used for sample statistics. Eg: x-bar is the sample mean
Yes, English and Greek characters (letters) are the most frequently used symbols for variables.
