Algebra is a branch of Mathematics that uses symbols (like x, y) to represent unknown values and relationships. Here are the key specifics: Variables & Constants: Letters (x, y) represent unknowns; numbers are fixed values. Expressions: Combinations like 3x + 5 (no equals sign). Equations: Statements like 2x + 3 = 7 that can be…

When we divide 100 by 3 we get 33.33333… ( 100 / 3 = 33.33333… ) and when we multiply 33.33333… with 3 we get 99.99999… (33.333… 3 = 99.999…) Where does the 0.111… disappear?
