In subtraction, Dickson & al (1984) cite Resnick (1982) summary of student's most common When \(n = 3\), we call it the cube root. Hence, it can be concluded that difference of two whole numbers is not always a whole number. Two of the most common errors relate to the positioning of the numbers in the vertical presentation of the addition and the process of 'carrying'. Furthermore, irrational numbers are non-terminating and non-repeating, so imagine adding many decimal places to each natural number along with all the combinations of digits we can use for each of the decimal places, and you can start to imagine just how many more irrational numbers there are! Radicals such as \(\sqrt{2}\) are the most common type of irrational number. Number or expression inside the radical symbol (\(\sqrt{\phantom{x}}\)). IRRATIONAL NUMBERS An irrational number is any real number that cannot be expressed as a ratio a/b, where a and b are integers, with b non-zero, and therefore not a rational number.
