5+(2+3i)+(-3-7i)complex numbers?

⚑ Flag

Aamier -To tackle this kind of problem, simply fall back on what you know from Algebra.  Numbers are combined together with other numbers and variables are combined with similar variables.  So, for complex math addition and subtraction, simply add or subtract the "i" terms (just like a variable) and then separately combine the numbers.For example:(3 - 5i) - (2 + 7i) = (3 - 2) + (-5i - 7i) = 1 - 12iI'll leave the math for your problem for you to finish!Hope that help
