No, the statement "Every real number is an integer" is not correct.
To understand why, let's review the definitions of these terms:
1. Real number: A real number is a number that can be either rational or irrational. It includes numbers such as integers, fractions, decimals, and square roots of non-perfect squares.
2. Integer: An integer is a whole number without a fractional or decimal part. It includes zero, positive numbers (1, 2, 3, ...), and negative numbers (-1, -2, -3, ...).
The statement is incorrect because not every real number is an integer. For example, real numbers like 1.5, √2, and π are not integers. Integers are a subset of real numbers, but not all real numbers are integers.
