To make the statement "6 - 4 __ 1" true, you can use the operator "=".
So the statement would be:
6 - 4 = 1
This is true since 6 - 4 equals 2, which is not equal to 1. Therefore, the correct operator to make it true is ">", leading to:
6 - 4 > 1 2 > 1
This statement is true since 2 is greater than 1.
