UTILBIT's math tools apply the correct formula automatically and show the working, not just the final number.
The Scientific Calculator extends this to trigonometry, logarithms, exponents, and factorials with both degree and radian modes, while GPA/CGPA, Percentage, Discount, Simple Interest, and Tip calculators each focus on one common real-world calculation with a clear breakdown of every step.
