Expand description
Numbers allows us to express and compare magnitudes and quantities.
A number can be written in many different ways. For example, all of these expressions and numerals represent the same number:
$$ 4 \qquad 1\times 4 \qquad 4.00 \qquad \text{four} \qquad 3+1 \qquad \frac{28}{7} \qquad \sqrt{16} \qquad \sqrt[\footnotesize 3]{64} \qquad (-4)×(-1) \qquad 3.99… \qquad 2^2 \newline \text{\huge ⚃} \qquad \texttt{0b100} \qquad \text{11}_3 \qquad \text{Ⅳ} \qquad \text{𝍣} \qquad \text{𐄊} \qquad \text{⠙} \qquad \text{Δʹ} \qquad \text{四} \qquad \text{넷} \qquad \text{٤} \qquad \text{ד} \qquad \text{៤} \qquad \text{𒐂} \qquad \text{৪} \qquad $$
