Q. Is −4-4 a real number?\newlineChoices:\newline(A) yes\newline(B) no
  1. Define real numbers: Understand the definition of a real number.\newlineReal numbers include all the numbers on the number line, including all the rational and irrational numbers. Rational numbers are numbers that can be expressed as a fraction of two integers, and irrational numbers cannot be expressed as a simple fraction. Real numbers can be positive, negative, or zero.
  2. Evaluate −4-4: Determine if –4–4 meets the criteria of a real number. –4–4 is an integer, which is a subset of rational numbers since it can be expressed as –4/1–4/1, where both numerator and denominator are integers.
  3. Confirm −4-4 as real number: Conclude whether –4–4 is a real number based on its properties.\newlineSince –4–4 is an integer, and all integers are real numbers, –4–4 is indeed a real number.
