whats 2*2
That means 2 times 2. On this board, an asterisk is sometimes used as a multiplication symbol, especially where using an x as the multiplication symbol could get confused with an "x" used to represent an unknown in an equation.
x
Yes, but in \(\LaTeX\), you can use \(\times\)or \times.
People do mostly avoid using an x though.
Some people use a dot \(\cdot\) (\cdot in latex) but if you write that out, you might mistake it for a decimal point. So another alternate solution could be parentheses.
Example(s):
\(2(2)\text{ instead of }2\cdot 2 \text{ or } 2\times 2\)
Okay why am I writing a whole explanation lol.
