Examples
Typically, this error occurs in Worksheet mode using 1-D Math. For example, multiplication requires a * sign. For more operators, see arithmetic operator.
Also, all functions require parentheses around their arguments.
Example 1
2 x + y; # Worksheet mode using 1-D Math.
Error, missing operator or `;`
Solution
2*x + y;
2⁢x+y
Important: Implicit multiplication is permitted with 2-D Math input.
2 x + y ; # Any mode using 2-D Math
Functions require parentheses around their arguments.
