2+2=4 is only true so long as you are using the correct base. For instance in base 2(binary) 1+1=10. So even the simple mathematical equasion can be interpretted differently based on the system of measurement. 2+2 in base 4 would actually be 10. in base 3 it would be 11.
I was writing a sci fi novel with creatures that had three fingers per appendage, and had their countdown use 10, 5, 4, 3, 2, 1, 0(basing it off how we use base 10 cause we have 5 digits and 2 arms...).
