Adding and Subtracting Complex Numbers 2. 7

Today’s Objective • SWBAT add and subtract complex numbers.

Vocabulary – don’t need to write these down • • Sum = Difference = Product = Quotient =

Adding and Subtracting • Really, we are only combining like terms. 1. Circle the operation between the complex numbers. 2. If addition, add the real numbers and add the coefficients of the imaginary numbers. 3. If subtraction, distribute the negative, then add. 1. Change the – to a +. 2. Flip the signs of everything inside the second parentheses.

What about the EOC word problems? 1. Underline the key terms in the problem (sum, difference, etc. ) 2. Look for the “is” in the same sentence as “sum” or “difference” (comes after the equal sign) 3. Setup the problem. 4. Solve (inverse operations)!
