  1. 6. An equation that is true for all values of the variable, such as x + 0 = x.
  2. 8. A mathematical statement showing that two expressions are not equal using symbols like <, >, ≤, or ≥. For example, x > 5 indicates that x can take any value greater than 5.

  1. 1. A combination of numbers, variables, and operations without an equals sign. For example, 3x + 2 is an expression.
  2. 2. To write an expression in its simplest form by combining like terms or performing operations. For instance, simplifying 2x + 3x results in 5x.
  3. 3. A symbol, often a letter, that represents a number that can change. For example, in the equation y = 2x + 3, x is a variable that can take on different values.
  4. 4. A value that does not change, such as the number 5 or π. Constants are crucial in equations where fixed values are needed.
  5. 5. A mathematical statement showing that two expressions are equal, such as 2x + 3 = 7. Equations can be solved to find the value of the variable.
  6. 7. A part of an expression or equation separated by + or − signs. In the expression 3x + 2, there are two terms: 3x and 2.
