$(($C$21/$C$20)-$C$29)*$C$18,$ How would I put these in parenthesis if C$21/$c$20$ is $11\mathrm{.}45,$ c$29$ is $16,$ and c$18$ is $10,200.$ I am looking for $(11\mathrm{.}45-16)*10,200$ and to equal $46,410$ without cell refrences. I came up with $10,200$ on my calculator but am having trouble getting it with the cell refrences in excel.
