Delta F -> F is not printing properly.

'\text{Slope of line }\mathrm{AB}=\frac{\Delta{C}}{\Delta{F}}

\\=\frac{100-0}{212-32}=\frac{100}{180}=\frac{5}{9}

if we added the extra space after the Delta{F}} its working fine. Please refer the below letax. our expectation should work with above formula.. Please refer below screenshot. which is highlighted because u can understand the whitespace.
