(3-2i)-(4-3i)
Solved by pluggable solver: ARITHMETIC on Complex Numbers

Solution:Subtraction of two complex numbers a + bi
and c+di is done according to formula:


(a + bi) - (c+di) = (a+c) - (b+d)i.


In our case, %283+%2B+-2%2Ai%29+-+%284+%2B+-3%2Ai%29+%0D%0A+++=+%283+-+4%29+%2B+%28-2--3%29i++%0D%0A+++=+-1+%2B+1%2Ai



(4-2i)+(-50+3i)

-46 +1i.


Solution:Addition of two complex numbers a + bi
and c+di is done according to formula:



(a + bi) + (c+di) = (a+c) + (b+d)i.


In our case, %0D%0A++++%284+%2B+-2%2Ai%29+%2B+%28-50+%2B+3%2Ai%29+%0D%0A+++++=+%284%2B-50%29+%2B+%28-2%2B3%29%2Ai+=+-46%2B1%2Ai.
