Algebra 2 - Tutoring Algebra 2 Subtracting complex numbers (4+6i) - (-1+2i)

The video tutorial covers subtraction of complex numbers using vertical alignment and alternative methods. It explains the importance of aligning terms correctly and introduces an alternative method by converting subtraction into addition. The tutorial also demonstrates the use of the associative property to rearrange terms, ensuring the same result is achieved through different approaches.

What is the result of subtracting a negative number from a positive number?

• The result is always negative.

• The result is always zero.

• The result is always positive.

• The result is always the same as the positive number.

How can you convert a subtraction problem into an addition problem?

• By dividing all terms by two.

• By multiplying all terms by zero.

• By negating all the terms and adding them.

• By adding the same number twice.
