What equals 27 in addition?

Answer 1

There are an infinite number of solutions:

Start with two positive integers: 1 + 26, 2 + 25, 3 + 24 etc

Then try some negative integers: -1 + 28, -2 + 29 , -3 + 30 etc

Next try decimals (tenths): 1.1 + 25.9, 1.2 + 25.8, 1.3 + 25.7 etc

then try decimal (hundredths): 1.01 + 25.99, 1.02 + 25.98, etc

Finally some irrationals: 1+ sqrt(2), 26 - sqrt(2), 1+ sqrt(3), 26 - sqrt(3), etc
