Put the steps next to yours
Choose a calculator
Find a topic that fits your problem. Load a sample if you want to see how the inputs work.
Check the setup
Enter your known values and units. Make sure the calculator’s assumptions fit your problem.
Follow the calculation
Read the equations, substitutions and results. Where a diagram is included, use it to connect the numbers to the problem.
Compare with your work
Work through any differences in inputs, units or method. CivilSolve shows its calculation; it does not mark your written solution.
