Complete the equality to make it true:
1 1 1 1 = 5
- You can add any math operation or symbol to the left side.
- You cannot change right side nor the
=
(adding a previous<
or>
is considered changing it). - You can't add any number. Not even implicitly: i.e.
√x
isx0.5
so that would be adding numbers. - You can't combine the
1
s (not for integers like11
and not for decimals like1.1
).
