I think we can just use a minus sign.

I see  but on my assignment, it was considered right. Thanks everybody!!

$${\mathtt{4}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{0.574}}{\mathtt{\,\times\,}}{\mathtt{120}}{\mathtt{\,\times\,}}{\mathtt{1}}}{{\mathtt{8}}}} = {\frac{{\mathtt{1\,261}}}{{\mathtt{100}}}} = {\mathtt{12.61}}$$

Wow, this calculator is amazing. :O

Thanks you so much!!

Remember PEMDAS

50*1=50 

60*0=0

50-60=-10

-10+10=0

Sorry that you worked so hard, but this answer is incorrect. 

$${\frac{{\mathtt{2.2}}}{{\mathtt{0.333\: \!333}}}} = {\mathtt{6.600\: \!006\: \!600\: \!006\: \!6}}$$  Not sure if you wanted a non-terminating decimal

$${{\mathtt{55}}}^{{\mathtt{2}}} = {\mathtt{3\,025}}$$  Inches

$${\frac{{\mathtt{9}}}{{\mathtt{21}}}} = {\frac{{\mathtt{3}}}{{\mathtt{7}}}} = {\mathtt{0.428\: \!571\: \!428\: \!571\: \!428\: \!6}}$$

$${\frac{{\mathtt{8}}}{{\mathtt{14}}}} = {\frac{{\mathtt{4}}}{{\mathtt{7}}}} = {\mathtt{0.571\: \!428\: \!571\: \!428\: \!571\: \!4}}$$

Ooohhh! Now I understand what Melody meant by not having to type it all and just use the calculator to post the answer.
