Venn Diagram of ...May 25, 2021 · This seems like a lot of trouble for a simple sum, but it illustrates a powerful result that will be useful once we introduce algebraic terms. To subtract a sum of terms, change the sign of each term and add the results. With this in mind, we can rewrite the last example. 12 − (5 + 3) = 12 + ( − 5 − 3) = 12 − 8 = 4. An imaginary number is a real number multiplied by the imaginary unit i, which is defined by its property i 2 = −1. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.By definition, zero is considered to be both real and imaginary.

Some of the examples of real numbers are 23, -12, 6.99, 5/2, π, and so on.Any rational number can be represented as either: a terminating decimal: 15 8 = 1.875, or. a repeating decimal: 4 11 = 0.36363636⋯ = 0. ¯ 36. We use a line drawn over the repeating block of numbers instead of writing the group multiple times. Example 1.2.1: Writing Integers as Rational Numbers. For example, 0.1 in decimal — to 20 bits — is 0.00011001100110011001 in binary; 0.00011001100110011001 in binary is 0.09999942779541015625 in decimal.
