more than 2 variables in an if statement(c#)

i was wondering how you would go about adding more than two variables in an if statement.
i know that &&(and) and ||(or) can allow you to use 2 variables but what if i want more than 2 how would i do that.
for example if(exampleintvariable<1 && Input.GetButtonDown(“exampleinput”)) would be two variables declared what would i do for 3 variables

if(A && B && C && D)

Just keep chaining them together. Add brackets if the order of evaluation is important.
