1 is the 1 that is called 1. In terms of integers, it comes before 2 and after 0.
It could also be defined as the multiplicative identity of the "normal" number systems (integers, rationals, reals, complex numbers).
one one one
1 x 1 = 1 The answer is one.
-1/ (+)1 = -1
Inelegant solution. Maximum effort. 100-1-1-1-1-1-1-1= 99-1-1-1-1-1-1= 98-1-1-1-1-1= 97-1-1-1-1= 96-1-1-1= 95-1-1 94-1= 93 ..... ..... ..... ..... ..... ..... ..... ..... Elegant solution. Minimum effort. 100-1-1-1-1-1-1-1= 100-7= 93
1 1/3 minus 1/4 is 1 1/12
-1/-1 = (+)1
1 1/6 + 1 1/2 = 2 2/3
It is: (1 and 1/9) divided by 1/3 = 3 and 1/3
One and one half is the same as 1 and 1/2 or 1.5 one and one third is the same as 1 and 1/3 or 1.333 ad infinitum. 1 ⅓ + 1 ½ = 1 2/6 + 1 3/6 = 2 5/6 Or 1.83333 ad infinutum
one half of one sixth is one twelfth
Because one-half (1/2) + one-third (1/3) + one-quarter (1/4) = 1 and one-twelfth (1 1/12).
note: one quarter = 1/4 one half of one quarter of one tenth of 80:= 1/2 of 1/4 of 1/10 of 80= 1/2 x 1/4 x 1/10 x 80/1= 80/80= 1
