Can someone please explain Operators and Expressions?

It's really hard for me to understand the last episode of stage 1 in iOS development.

int sum = 2 + 3;

The plus sign ('+') would be the operator and the expression is basically what is used to define what the variable would be.

  1. 'int' is the data type.
  2. 'sum' is the variable name.
  3. '+' would be the operators.
  4. expression would be 2 + 3 which would give the variable named "sum", the value of 5.
