What's an Inequality?

Definition: An inequality occurs when we have two values that are not equal to each other, but still have a relationship.

Summary

  1. '<' is the less than symbol
  2. '>' is the greater than symbol
  3. '≠' is the not equal to symbol
  4. '≤' is the less than or equal to symbol
  5. '≥' is the greater than or equal to symbol
  6. x and y are both unknown numbers called variables
  7. If x is less than y, then we know for sure that y is bigger than x

Notes

    1. The '<' is the less than symbol
    1. The '>' is the greater than symbol
    1. The '≠' is the not equal to symbol
    1. The '≤' is the less than or equal to symbol
    1. The '≥' is the greater than or equal to symbol
    1. Switching the sides of the inequality, switches the direction of the inequality
    2. If x<y, and we switch the 'x' and 'y', then y>x
    1. 5 is less than 7
    2. We also know that 7 is greater than 5
    3. x is greater than or equal to 10
    4. Also, 10 is less than or equal to x
    5. x an unknown number called a variable
