A mathematical approach:Yes they are. Irrational Numbers are very real, for example - the square root of two - which is irrational (but can be plotted in a number line without difficulty with a compass and straight edge). All numbers you can think of (even if you cant white them out) are real numbers.They are real, but they can't be expressed as fractions.A philosophical approach:According to ME, there should be a limit. If there is a number which is not ending, we can't say that it is a number because it has not ended yet, its not a complete number. That's why, any number which is not ending is not a number, so irrational numbers and some rational numbers are not numbers and we can't plot them on real line, no matter how much depth we are into it. If there is a number 1.0000... (100 million 0's) ...1, we can plot it by dividing real line into required many parts but we cant plot a number like 1.1111....1111....(up to, we don't know), actually that's not a number yet.Maths should be changed.

Just choose some number (preferably a whole number), and multiply both 11 and 4 by this number.

0.222 = 1111/5000

1111 + 0001 + 1000 + 0100 = 11100 Remember that in binary, 1 + 1 = 10 (0 carry 1) and 1 + 1 + 1 = 11 (1 carry 1).

It wasn't possible last week and it still isn't possible for 6 odd numbers to add to an odd number, so... Cheat! 3 + 3 + 3 + 1 + 11 = 21
