To make a negative, just hit the - symbol....for example (-1)

$${{\mathtt{8}}}^{{\mathtt{2.666\: \!666\: \!666\: \!666\: \!666\: \!7}}} = {\mathtt{256}}$$

Hey yall!  Let's make 300!

Exactly what Geno said, it can't be a decimal or fraction!!!

29/197 is the fraction

$$\left({\mathtt{7}}{\mathtt{\,\times\,}}-{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}-{\mathtt{5}}\right) = {\mathtt{280}}$$

Sure thing!!!!

Yep!

$${\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{317\,000\,000\,000}} = {\mathtt{1\,268\,000\,000\,000}}$$

Did I help you?
