-1 OR 5*5=26

Do you mean bitwise OR (as in programming) or logical OR (booleans), and do you want to know if the equation is true, or to compute the left-hand side?

Here are the common interpretations:

• Bitwise OR: -1 | (5*5)

  • 5*5 = 25
  • In two's complement, -1 is all bits 1. Bitwise OR with any number yields -1.
  • So -1 | 25 = -1, not 26. The statement "-1 OR 5*5 = 26" is false.

• Logical OR (truth values): (-1) OR (5*5)

  • -1 is considered true; 5*5 = 25 is also true.
  • True OR True is true. But “equals 26” doesn’t fit boolean logic (true isn’t 26).

If you were aiming for 26, a natural way is 5*5 + 1 = 26 (i.e., add 1 to 25). If you want, I can tailor to the exact language (C, Python, etc.) or give more practice problems. Which interpretation should I use?
