# 1 1 11 Meaning ### What’s the reasoning that lies behind

The conventional equation 1+1 = 2. is true (sometimes! )Binary 1+1 = 10.. There isn’t a binary 2.
Boolean logic 1 and 1 = 1. This means the True, True will always be true (see further).

Roman and Egyptian 1  + 11 = 11 in unary numeral systems, the number two is represented as the symbol of one twice.

Greek + = Iota is the symbol that represents 10. Kappa, or kappa, is twenty.

Mod 2 + 1 = 0 and the arithmetic can be described as circular. In the case of Mod 2, you divide by 2 and then you get the remaining. Thus 25 mod 2 is 1, and 12 mod 2 is 0.

A round of 1+1 =3 It might be a surprise to you! However, you can achieve this effect using rounding. 1.4 + 1.4 = 2.8. However, if every number is then rounded to the nearest whole number you have 1+1 =3. Test it out on the calculator that calculates arithmetic to full numbers.

BODMAS 1 + 1 x 2 = 3.
Not 4

If you substitute 1+1 for 2 prior to doing the multiplication, you’ll be given the wrong answer 4.

### Bottom Lines

“If there was a problem with one and one wasn’t sure the best way to handle it, one would be lost. …” There is no way to replace one or one with two! Okay, this is a fun little piece of entertainment! However, it also demonstrates essential concepts. It is important to realize that rounding can result in unexpected results as previously mentioned.

This can occur in the real world. For instance, if you write a report on money, and then round according to the nearest unit, and then take the unrounded amount and then round it up to the closest pound you might receive a different result than when you add the rounded money. It could be better to use the word plus instead of and if that’s the case, to ensure you do not get confused by using Boolean AND.
