Key Topics to Revise

1

Core Ideas and Definitions

  • An equation is a statement of equality between two expressions.
  • An inequation states that one quantity is either less than or greater than another quantity.
  • A linear inequation has each variable in first degree only and no term involving the product of variables.
2

Rules of Inequality and Interval Notation

  • If the same number or expression is added to or subtracted from both sides of an inequation, the sign of inequality remains the same.
  • If both sides are multiplied or divided by the same positive number, the sign remains the same.
  • If both sides are multiplied or divided by the same negative number, the sign of inequality is reversed.
3

Worked Examples and Standard Question Types

  • 13x<200 gives different solution sets for different replacement sets.
  • 7+3x≤35-2x with whole numbers gives a finite solution set.
  • 2x-3/2≥6-5x with integers gives all integers from 2 onward.
