Algebraic expressions consist of variables, constants, and arithmetic operations. They are used to represent mathematical relationships symbolically.
Linear equations are equations of the first degree. Solving linear equations involves finding the value of variables that satisfy the equation.
Quadratic equations are second-degree equations generally expressed in the form ax² + bx + c = 0. They are solved using factorization or the quadratic formula.
Logarithms are the inverse of exponential functions and are useful in simplifying complex calculations in pharmaceutical sciences.
