Definitions: ∞ is a collection of variables and constants. ∞ it is formed by combining numbers and variables using any of the four fundamental operations ( +, -, ×, ÷ ), powers and roots. 3x + 2y 6 + 9x – 3y 4j + 2 j 2 - 4

VARIABLEs  are letters used to represent certain values or quantities.  It has no fixed value. CONSTANT  A symbol with a fixed qualitative value.

A TERM in an algebraic expression are numbers and letters combined by multiplication that serves as its operation. It may have a variable term or a constant term.

Constants or Constant Terms ~ are the terms that have no variables, only numbers. They are called constants because their values never change since there are no variables in the term that can change its value. Variable Terms ~ are terms combining numbers and variables.

Example: 5x 2 variable terms + 3xy+26 constant term &

The number parts of each term which is and is the NUMERICAL COEFFICIENTS of each of the variable terms. However, and are the LITERAL COEFFICIENTS. The number of terms of an algebraic expression is determined by the plus and minus operations. 5 x 2 3 xy

39x 7 y 5 z constant term 39x 7 y 5 z 2 variable term 39 numerical coefficient of x 7 y 5 z 2 x, y, z variables x7y5z2x7y5z2 literal coefficient of 39 There are two terms since 39x 7 y 5 z 2 and 12 are separated by “+” operation.
