3*4+-7=5 and 10=8/2+6 cover everything but 9.

  Ooh, that is good. I figured that +- would be invalid but nerdle accepts it.

  9 * 6 - 3 = 51 and 28 / 4 + 0 = 7 will cover everything and allow you to determine the = position.

    That is fantastic, kudos to you for finding a way to cover those extra two digits. I am going to use this opener.
