Question 1
1.1. Real vs. Non-Real Numbers
Real Numbers: Real numbers are any numbers that can be
found on the number line. This includes all the numbers we use
in everyday life.
Examples:
1. 2: This is a real number because it can be placed on the
number line between 1 and 3.
2. -4.5: This is also a real number because it can be placed on
the number line between -4 and -5.
, Non-Real Numbers: Non-real numbers are numbers that cannot
be found on the number line. They are often complex numbers
which include imaginary parts.
Examples:
1. √(-1): This is a non-real number because you cannot take
the square root of a negative number in the real number
system. It is known as an imaginary unit (i).
2. 3 + 2i: This is a non-real number because it has an
imaginary part (2i) along with the real part (3).
1.2. Rational vs. Irrational Numbers
Rational Numbers: Rational numbers are numbers that can be
written as a fraction where both the numerator and the
denominator are integers, and the denominator is not zero.
Examples:
1. 1/2: This is a rational number because it can be expressed
as a fraction (1 divided by 2).
2. -3: This is a rational number because it can be written as -
3/1.
Irrational Numbers: Irrational numbers are numbers that
cannot be written as a simple fraction. Their decimal
representation goes on forever without repeating.
