    The difference of twice a number and 6 is at most 28

    This is an algebraic expression. Let's take it in parts:

    1. The phrase a number, means an arbitrary variable, let's call it x
    2. Twice this number means we multiply x by 2: 2x
    3. The difference of means subtract, so we subtract 6 to 2x: 2x - 6
    4. Is at most means less than or equal to, so we create an inequality where 2x - 6 is less than or equal to 28, using the <= sign
    2x - 6 <= 28
