63. ¿Por qué se usan LETRAS en álgebra? (Variables, literales, incógnitas)

▼ IMPORTANT ▼ In this video I will give a brief explanation of why it is convenient to use variables in mathematics, I will explain it by giving some examples of problems that we can only solve with the use of variables, and also showing formulas for areas, or speed in physics, or the Pythagorean theorem, expressed in the form of an equation with variables, more conveniently. #algebra #secondary #expressions ---------- ** IMPORTANT LINKS ** Elementary Algebra Course:    • Curso Completo de Álgebra   Special Videos:    • Members-only videos   Mathematics Review Course (Pre-University)    • Curso de Repaso de Matemáticas   ---------- ** SEE ALL MY COURSES HERE **    / arquimedes1075   ---------- ** BIBLIOGRAPHY ** Algebra, Lehmann Algebra, Baldor Simplified Mathematics, by Conamat ---------- ** DONATIONS ** Paypal: https://www.paypal.com/cgi-bin/webscr...
