Correct answer is (a) True

Explanation: In numerical analysis, Simpson’s rule is a method for numerical integration, the numerical approximation of definite integrals. The slide rule, also known colloquially in the United States as a slipstick, is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for functions such as exponents, roots, logarithms and trigonometry, but typically not for addition or subtraction.
