• Let z1=a+ib and z2=c+id.
• The difference of two complex number is:Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle (a+ib)-(c+id)=(a-c)+(b-d)i } where a,b,c and d are real numbers.
• We can use COMPLEX function to convert real and imaginary number in to a complex number.

Examples

1. IMSUB("6+4i","5+3i")=1+1i
2. IMSUB("3+4i","6+7i")=-3-3i
3. IMSUB("8","9+10i")=-1-10i
4. IMSUB("5+7i","3")=2+7i
