$(8 + 7i) - (5 - 3i)$

$\longrightarrow \: (8 + 7i - 5 + 3i)$

$\longrightarrow \: (3 + 10i)$

3+10i is the difference between the current of the two circuits

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A mixed fraction is a fraction that is made up of a whole number and a proper fraction. A proper fraction is a number where the numerator is less than the denominator.

The worth of the stock now = purchase price + increase in the share price

28 1/8 + 6 5/8

$34 \frac{1 + 5}{8}$
