error: CS1525: Invalid expression term '<'

Hello. I don’t know what I do wrong but I get the error "CS1525: Invalid expression term ‘<’ " when trying to do some if + greater than / less than statements.

Here are some variables that are not visible in the pic.

public transform tf; 
public rigidbody rb; 
Kiirus = rb.velocity

The error code

    void KinnijäämiseParandus()
    {
    
        if(kiirus =< 13)
        {
            tf.position = tf.position + (0, 0, 1);
        }


}

Please note that some variables and stuff are not in English, that’s because I like using my home language, especially at public variables.

The problem is

if(kiirus =< 13)
         {
             tf.position = tf.position + (0, 0, 1);
         }

you are trying to say Equal To or Less Than… The proper operator is Less Than or Equal To :

if(kiirus <= 13)
         {
             tf.position = tf.position + (0, 0, 1);
         }
