Question 181595
<font face="Times New Roman" size="+2">


The simple answer is <i><b>never</b></i> subtract.  <i><b>Always</b></i> add the additive inverse.  So, instead of:


*[tex \LARGE \text{          }\math (3-i)-(-4+9i)]


Write:


*[tex \LARGE \text{          }\math (3-i)+ \left(-(-4+9i)\right)]


Use the distributive property:


*[tex \LARGE \text{          }\math (3-i)+ (4-9i)]


And now you can add just like before.
