-1 OR 5*5=26 --

It looks like a small puzzle or a typo. Here’s how to parse it.

• First, correct the arithmetic: 5 × 5 = 25, not 26.

• If “OR” means bitwise OR between integers (a common exam context):

  • -1 in two’s complement is all bits set (…111111).
  • -1 | 25 = -1, because OR with a value that has any 1s and a word of all 1s still yields all 1s.
  • So the expression -1 OR 5*5 equals -1, not 26.

• If “OR” is meant as a logical OR on booleans, you’d typically only have true/false, not 26, so that interpretation wouldn’t give 26 either.

So the statement “-1 OR 5*5 = 26” is false under standard interpretations. The correct evaluation is:

• 5*5 = 25
• -1 | 25 = -1 (bitwise OR)

Would you like me to show this in a specific programming language (e.g., Python, C, Java) or walk through the boolean/logical interpretation as well?
