Your objective is to change one constant in the following equation so that it equates to true.


  • No changing the equals sign.
  • The numbers are correct.
  • There only needs to be one change in order to make the equation true.

142 / 2930 = 142

    $\begingroup$ The tag is substitution, so the "change" should be to replace something, and since the numbers are correct and I can't touch the equals sign, that only leaves the divisor, no? Or are the numbers correct, just in the wrong positions? $\endgroup$

You can change

the division operator (/) to the modulo operator (%)

The resulting equation

142 % 2930 = 142

is certainly true.


If you can move up the 0 to become an exponent, you get:

$$ 142 / 239^0 = 142 $$

This works since $239^0 = 1$.


A slightly different answer just to add on:

The division symbol could be moved over top of 2930 to appear as a strikethrough. If this is done, $142=142$ with some extra numbers that had to be crossed out and are ignored.


You can also replace the space after / by a second / You then have 142 with a line comment, which, when casted into a boolean gives true as it is a nonzero number
